RK3588 Custom Core Board Multi-Serial, WF-C3588-I1, AndroidSBC, Lisbon

TL;DR: RK3588 Custom Core Board Multi-Serial

SHENZHEN, China, September 12, 2026 - The WF-C3588-I1 board cleared the Longgang aging bench this week in lot 331, a 25,735-unit run for Lisbon, Portugal, and moved straight to the container yard.

AndroidSBC benchmark note covering the WF-C3588 custom motherboard line serving Lisbon, Portugal. The WF-C3588 line is a custom motherboard programme built on the Rockchip RK3588 octa-core platform (4x Cortex-A76 at 2.4GHz plus 4x Cortex-A55 at 1.8GHz on 8nm) with a triple-core NPU delivering 6 TOPS of INT8 inference, 8K H.265 decode and up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, builds nine custom variants at the Longgang source factory in Shenzhen for Lisbon and Portugal buyers: WF-C3588-A0 custom Android motherboards, WF-C3588-I1 custom industrial boards, WF-C3588-M2 core boards and SOMs with carrier design, WF-C3588-S3 custom signage and video wall boards, WF-C3588-K4 custom kiosk and POS boards, WF-C3588-R5 custom robotics controllers, WF-C3588-N6 custom NVR boards, WF-C3588-E7 custom edge AI boards, and WF-C3588-P8 custom ARM PC and NAS boards.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-C3588 is a nine-variant custom motherboard programme from AndroidSBC, the export arm of Wanlin Manufacturing Group in Shenzhen. One Rockchip RK3588 silicon, nine custom categories: custom Android motherboards, custom industrial boards, core board and SOM work, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant handles SMT, burn-in and pre-shipment inspection in one building, and the export desk handles the CE, FCC, UKCA, RoHS and IEC 62368-1 file per lot. For Portugal importers, the line covers the custom board categories a Lisbon distributor is most often asked to quote.

WF-C3588-I1 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For Portugal importers sourcing the WF-Series, the 8GB + 32GB (WF-C3588-I1-B) variant is the typical configuration for the custom industrial control and HMI programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Industrial Motherboard for Fanless and Wide-Temperature Control for Portugal Buyers

Buyers in Lisbon who have run the custom industrial motherboard for fanless and wide-temperature control category for a few years tend to stop shopping on price alone. The Rockchip RK3588 allocation is the real constraint, and it is the reason a 25,735-unit order can look cheap on paper and expensive in a slipped quarter. Then comes the firmware question. The hardware spec is straightforward to verify; whether the board holds a credential-locked stack through a 72-hour loop and a field OTA is a different test, and it is normally the Lisbon buyer's warehouse that discovers the answer.

Documentation closes the list. Buyers in Lisbon have learned to ask for the test reports before the deposit, because a CE mark printed on a carton is worth nothing at the port without the Declaration of Conformity behind it. AndroidSBC moves all three risks inside the factory: the custom variant is assembled at Longgang, the certified image is burned on the same line, and the Technical File ships with the lot. Across the nine WF-C3588 variants the coverage runs from industrial HMIs, panel PCs, PLC upgrades, SCADA nodes, DIN-rail controllers, factory automation, data acquisition, IIoT gateways, and machine control, with three memory configurations per variant, so a Lisbon buyer can usually match a requirement from the standard custom range.

On the Portugal side, the destination file matters as much as the board specification. In Portugal the market is served by Lisbon and Porto distributors who also cover the Portuguese-speaking markets in Africa and South America. The export desk prepares the destination-market file covering CE marking with ANACOM radio interface notification, administered by ANACOM, and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH). The lot is booked into Port of Sines on the Sines to Yantian lane.

Competitive Comparison: WF-C3588-I1 vs Competing RK3588 Boards

The comparison set for the custom industrial motherboard for fanless and wide-temperature control socket splits three ways: catalogue boards priced low with fixed everything, re-badged boards that cannot answer a schematic question, and custom platforms that take the I/O, memory and firmware changes in stride. The WF-C3588-I1 sits in the third group, differentiated by Rockchip RK3588, by customization depth, and by the factory-side certified image burn.

• vs commercial boards in industrial dress: the WF-C3588-I1 is designed to -40C to 85C from the schematic up, not a consumer board with a bigger heatsink.
• vs local integrator bundles: the carrier design, the BSP port and the DIN-rail chassis all come from one Longgang engineering desk, so responsibility never splits across vendors.
• vs legacy PLC upgrade paths: the 6 TOPS NPU adds on-device vision and predictive maintenance to a PLC retrofit without a separate AI box.
• vs trading-company boards: the per-lot Technical File, the aging record and the EMC pre-compliance bench all live inside the source factory.

Global Custom Industrial Motherboard and Panel PC Market Trends

Order timing in Lisbon now tracks the Custom Industrial Motherboard and Panel PC curve rather than the calendar-year budget. MarketsandMarkets sizes the Edge AI hardware segment at USD 26.9 billion for 2025 with a 32.7 percent CAGR through 2030 (MarketsandMarkets, 2025-2030), the silicon baseline that Portugal buyers keep on the desk when they negotiate custom board allocation. Three patterns are visible in the WF-C3588 book:

• Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-I1 board carries that headroom without a board change.
• SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.

For the Custom Industrial Motherboard and Panel PC category the practical signal in Portugal is that framework agreements are replacing spot buying, and the agreements are getting longer.

Taken together, the three patterns explain why Portugal buyers are moving from single orders to twelve-month framework agreements with a monthly lot cadence, especially on custom board programmes that cannot absorb a supply gap.

Partner Success Story: Meridian Kiosk Systems in Lisbon, Portugal

Meridian Kiosk Systems, a self-service kiosk manufacturer serving the Portugal market, deployed 6,300 custom WF-C3588-K4 kiosk boards for an ordering-terminal estate. The rollout covered the industrial hmi panel, scada edge node, and factory automation cell workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 6,300 custom WF-C3588-K4 kiosk boards for an ordering-terminal estate
• Region: Lisbon, Portugal
• Models used: WF-C3588-I1 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant
• Logistics: FOB Nansha with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Sines via the Sines to Yantian lane

"The kiosk ROM was the difference. Locked launcher, our APK pre-installed, payment profile signed at the factory. Our field failure rate halved because the board arrives as a finished terminal brain, not a dev kit wearing a label."

- Camila Fuentes, Operations Lead

Field Report: the aging and EMC pre-compliance bench at the Wanlin Longgang plant, where 25,735 units of the WF-C3588-I1 board are being screened before the Lisbon shipment

Reporter Li Jian, on the ground in Lisbon, Portugal. The bench ran the lot through a 168-hour aging cycle with periodic power cycling, then moved a sample set to the pre-compliance chamber for radiated emissions and ESD strikes. The WF-C3588-I1 boards cleared the internal limits with margin, and the results went straight into the lot's Technical File.

Radiated emissions on the sampled units came in below the internal limit with margin, which the compliance engineer noted as consistent with the last four lots.

The inspection confirmed three things on the spot: the WF-C3588-I1 units hold the burn-in with a yield above 99.06 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering CE marking with ANACOM radio interface notification administered by ANACOM, cleared for entry at Port of Sines on the Sines to Yantian lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Portugal importers can hand straight to their customs broker.

WF-C3588-I1 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) as the lead SKU for Lisbon and Portugal programmes:

• Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
• PLC upgrade retrofit: a plant keeps the field wiring and swaps the controller for a CAN-equipped board with Modbus passthrough.
• SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.
• Machine vision inspection: the 6 TOPS NPU runs defect classification at line speed on a 3.5-inch SBC inside the cabinet.
• Data acquisition gateway: a multi-serial variant logs sensor traffic from RS485 chains and buffers it during link loss.
• Factory automation cell: a systems integrator drives a robot cell and its safety stack from one wide-temperature board.
• Outdoor kiosk controller: an unattended terminal survives summer heat in a sealed enclosure with no fan to clog.
• Predictive maintenance: vibration and acoustic models run locally on the NPU and alarm before the PLC does.

Partnership Models for Lisbon Buyers

For Lisbon importers and brand owners, the WF-C3588-I1 and the rest of the WF-C3588 custom variants are available under three contract shapes:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

Whichever tier a Portugal partner picks, the goods leave Longgang with one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. The usual first order on the WF-C3588-I1 is the 8GB + 32GB (WF-C3588-I1-B) configuration at MOQ 5,000 units, samples in 1-3 days on standard variants and 15-30 days to mass production.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: Practically the layers that decide whether the board fits your product: the PCB layout and outline, the memory and storage fit (4GB to 32GB LPDDR4X/LPDDR5, eMMC to 128GB plus NVMe or SATA), the display interface mix (HDMI 2.1, DP 1.4, LVDS/eDP/MIPI), the I/O bank (CAN, RS232/RS485 multi-serial, relays, digital I/O), the wireless stack, and the enclosure or DIN-rail chassis. On top of that sit the firmware options: custom Android ROM with a locked launcher, custom Linux or Yocto image, pre-installed applications, custom boot animation and OTA updates. A Portugal buyer can start from a standard WF-C3588 variant and change one layer, or bring a full schematic and have the carrier designed from scratch.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes, and that work stays in-house. The ODM tier covers custom Android ROM builds with proprietary services and launchers, AOSP builds without Google services, and Linux images on Ubuntu, Debian, Yocto or Buildroot. BSP ports for custom carrier boards are executed by the Longgang engineering desk, with SDK and BSP source released to the partner under NDA. The same desk handles driver development for the I/O you added, which is the part that usually stalls when a factory forwards a vendor drop and walks away.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: Yes. Custom NPU development covers RKNN model deployment, quantization from the major frameworks, multi-model pipelines on the triple-core NPU, and custom AI algorithm integration. The desk validates throughput on your exact memory configuration, and the deployment lands as a versioned RKNN file that OTA can update in the field, which is how Portugal partners iterate models without replacing hardware.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: Samples of standard variants leave the factory in 1-3 days. Custom builds run 15-30 days to mass production once the design is signed off, with the schematic review and carrier design handled in the same window. MOQ sits at 5,000 units per shipment on standard configurations, custom runs are quoted against volume, and small pilot batches are accepted for first-article programmes.

What certifications does a custom board need for Portugal, and who handles them?

Answer: AndroidSBC handles them at the factory. Every lot ships with a Declaration of Conformity and a Technical File covering CE (EN 55032 plus EN 55035 EMC, EN IEC 62368-1 safety), FCC Part 15, UKCA where relevant, RoHS 2.0 and the REACH declaration, all dated within the prior twelve months. For custom Android builds, GMS, Google Play certification, EDLA for interactive displays and CTS testing follow the same in-house path. Where a Portugal market needs an additional national mark, the export desk confirms coverage before the order is confirmed rather than after.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum supply, patches maintained across the firmware lines, OTA for firmware and NPU model updates. For a Portugal programme running a custom board in the field, that commitment is written into the agreement at signature, which is what separates a source factory from a catalogue reseller.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-C3588-I1 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit record means the failure report usually carries a root cause alongside the replacement, which is what a Portugal integrator running a custom configuration actually needs.
