RTC Real-Time Clock Board, WF-RK3588-R2, AndroidSBC, Lisbon

TL;DR: RTC Real-Time Clock Board

Lisbon, Portugal - September 11, 2026. A 35,740-unit consignment of WF-RK3588-R2 boards left the Wanlin Longgang source factory for Lisbon this week, the 285th production lot released on the Rockchip RK3588 line.

AndroidSBC shipping and Incoterm briefing for WF-RK3588 NPU board orders serving Lisbon, Portugal. AndroidSBC is releasing the full WF-RK3588 NPU computing line for Lisbon and Portugal: nine variants built on the Rockchip RK3588 octa-core 6 TOPS NPU platform, covering edge AI inference, industrial machine vision, robotics and AMR controllers, AI NVR with analytics, smart cockpit, 8K digital signage, kiosk and POS, ARM PC and mini-PC, plus the SMARC 2.2 SOM for carrier-board work. The line ships from the Wanlin Longgang facility with OEM branding, ODM carrier work, and per-lot CE, FCC, UKCA, RoHS and IEC 62368-1 documentation handled in-house.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-RK3588 exists because Portugal buyers kept asking one supplier for two different NPU tiers. Wanlin Manufacturing Group answered by putting nine application variants on the same Rockchip RK3588 octa-core silicon with 6 TOPS NPU, 8K H.265 video and up to 32GB of LPDDR5. The group runs SMT, burn-in and pre-compliance testing in one Longgang building in Shenzhen, and the export desk holds the certification file rather than passing it back to the importer. For a Lisbon distributor that means one vendor file, one document format and one MOQ structure across the variants it sells.

WF-RK3588-R2 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3588-R2 (Robotics and AGV AMR Controller) 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 + 64GB (WF-RK3588-R2-A) variant is the typical configuration for the robotics controller and AGV AMR compute use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Robotics and AGV AMR Controller for Portugal Buyers

The recurring problem for Lisbon and Portugal buyers sourcing a robotics and agv amr controller is not the headline unit price, it is whether the allocation actually holds. The Rockchip RK3588 needs its own wafer slot, and brokers who quote from stock frequently cannot honour that slot once a 35,740-unit push lands mid-quarter. Then comes the software layer. A board that boots is not a board that holds a certified stack under a 72-hour loop, and Portugal buyers typically find the difference in their own warehouse rather than at the factory.

Documentation closes the list. Buyers in Lisbon have learned to request the test reports before releasing the deposit, because a mark printed on a carton carries no weight at the port if the Technical File behind it does not exist. AndroidSBC handles it by doing the software burn and the documentation at the factory: every lot leaves Longgang with the certified image loaded, a unit-level burn-in barcode, and a Technical File that carries the test reports. The nine WF-RK3588 variants cover robotics controller, service robot motherboard, AGV control, AMR autonomous mobile robot, quadruped robot, delivery robot, cleaning robot, SLAM navigation, robot vision fusion, and ROS2 compute node with three memory configurations each, which means a Lisbon integrator can usually match a customer requirement without a custom run.

For Portugal specifically, the file travels with the goods. In Portugal the market is served by Lisbon and Porto distributors who also cover the Portuguese-speaking markets in Africa and South America. AndroidSBC prepares the CE marking with ANACOM radio interface notification documentation for ANACOM, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Sines on the Sines to Yantian lane.

Competitive Comparison: WF-RK3588-R2 vs Competing RK3588 Boards

The boards competing for the same socket in the robotics and agv amr controller segment fall into three groups: low-cost Cortex-A53 boards without a usable NPU, mainstream Cortex-A55 boards with a 1 to 2 TOPS NPU and limited decode ceiling, and 64-bit octa-core boards with a real 6 TOPS NPU and 8K decode. The WF-RK3588-R2 sits in the third group and adds three things: Rockchip RK3588 silicon, a thermal envelope that survives a continuous NPU+decoder loop, and the per-lot certified image burn at Longgang.

• vs quad-core Cortex-A55 robot boards: the WF-RK3588-R2 octa-core cluster plus 6 TOPS NPU lifts SLAM update rates and obstacle response times materially.
• vs x86 robot controllers: the WF-RK3588-R2 fanless design holds -40C to 85C without active cooling and the BOM stays under the x86 reference.
• vs 1 TOPS NPU boards: the WF-RK3588-R2 triple-core NPU runs the obstacle model and the SLAM front-end in parallel on the same silicon.
• vs single-purpose AGV PLCs: the WF-RK3588-R2 pairs EtherCAT master with ROS2 to support both motion and perception on one board.

Global Robotics and Autonomous Mobile Robot Market Trends

The Robotics and Autonomous Mobile Robot market sets the pace for Lisbon procurement this year, and it does not move on its own. The Edge AI hardware segment that MarketsandMarkets values at USD 26.9 billion in 2025, with a 32.7 percent CAGR reaching USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030), sets the silicon allocation backdrop that NPU computing board buyers also compete for. Three patterns stand out in the WF-RK3588 order book for Portugal:

• Service robot motherboard: WF-RK3588-R2 drives the 360-degree vision fusion plus the speech pipeline on the same NPU.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588-R2 board carries that headroom without a board change.
• AMR autonomous mobile robot: WF-RK3588-R2 keeps a stable frame interval even when the SLAM map exceeds 100k landmarks.

Channel analysts tracking the Robotics and Autonomous Mobile Robot category note that allocation discipline, not unit price, has become the deciding factor for buyers who need a twelve-month programme to hold.

The common thread in Portugal is that single orders are being replaced by blanket agreements with a monthly release, because a programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.

Partner Success Story: Pacifica Mobility Systems in Lisbon, Portugal

Pacifica Mobility Systems, a smart cockpit and in-vehicle AI supplier serving the Portugal market, deployed 5,300 units of the WF-RK3588-C4 smart cockpit board for a regional transit fleet. The rollout covered the service robot motherboard, amr autonomous mobile robot, and cleaning robot workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 5,300 units of the WF-RK3588-C4 smart cockpit board for a regional transit fleet
• Region: Lisbon, Portugal
• Models used: WF-RK3588-R2 (lead SKU), plus eight sibling WF-RK3588 NPU variants in the same chassis 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

"Driver monitoring, occupant detection and a four-display digital cockpit on one board is what let us drop the add-in card entirely. The vehicle power tolerance and the wide-temperature rating on the WF-RK3588-C4 are the two specification lines that decided the tender."

- Yasmine El-Sayed, IT Director

Field Report: the aging and EMC pre-compliance bench at the Wanlin Longgang plant, where 35,740 units of the WF-RK3588-R2 board are being screened before the Lisbon shipment

Reporter Zhao Lei, 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-RK3588-R2 boards cleared the internal limits with margin, and the results went straight into the lot's Technical File.

The plant maintenance log showed no unscheduled stoppage on the Rockchip RK3588 line during the lot, which the production manager attributed to the AOI pass added last quarter.

The inspection confirmed three things on the spot: the WF-RK3588-R2 units hold the burn-in with a yield above 99.35 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 Rockchip RK3588 NPU computing line with a per-lot paper trail that Portugal importers can hand straight to their customs broker.

WF-RK3588-R2 Application Scenarios

The WF-RK3588 line fits nine NPU application lanes, with the WF-RK3588-R2 (Robotics and AGV AMR Controller) as the lead SKU for Lisbon and Portugal programmes:

• Service robot motherboard: WF-RK3588-R2 drives the 360-degree vision fusion plus the speech pipeline on the same NPU.
• AGV control board: WF-RK3588-R2 holds the SLAM front-end while the EtherCAT master drives the wheel controllers.
• AMR autonomous mobile robot: WF-RK3588-R2 keeps a stable frame interval even when the SLAM map exceeds 100k landmarks.
• Quadruped robot: WF-RK3588-R2 runs the gait controller plus the perception stack on one octa-core cluster.
• Delivery robot: WF-RK3588-R2 holds the elevator interface plus the obstacle model on the same board.
• Cleaning robot: WF-RK3588-R2 fuses mmWave radar with the vision input to detect glass and dark obstacles.
• SLAM navigation: WF-RK3588-R2 ingests two MIPI CSI feeds plus the IMU at the full SLAM rate.
• ROS2 compute node: WF-RK3588-R2 runs the perception, planning, and control nodes on the same silicon with hardware isolation.

Partnership Models for Lisbon Buyers

The WF-RK3588 line is available to Portugal partners through three routes, and they can be mixed inside one agreement:

• 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.

All three tiers ship from Longgang under one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. A Lisbon first order on the WF-RK3588-R2 is normally the 8GB + 64GB (WF-RK3588-R2-A) configuration at MOQ 5,000 units per shipment, four weeks for samples and six weeks for mass production.

Frequently Asked Questions

Does the WF-RK3588 line run Android or Linux, and what NPU framework stack is supported?

Answer: Both. AndroidSBC prebuilt Android 12 and Android 13 firmware images that boot on every WF-RK3588 variant, with Android 14 builds available on request. Linux distributions (Ubuntu 22.04 LTS, Debian 12, Yocto Kirkstone, Buildroot) load the Rockchip RKNN-Toolkit2 runtime so the 6 TOPS NPU is usable from day one. The same silicon carries the Android build on the WF-RK3588-D5 signage player and the Yocto build on the WF-RK3588-V1 industrial vision processor, which is a deployment breadth that Portugal importers rarely get from one supplier.

What is the 6 TOPS triple-core NPU on the WF-RK3588 actually used for in production?

Answer: Three workloads that have already shipped at scale. On the WF-RK3588-E0 the NPU drives retail analytics (people counting, dwell time, demographic classification) at 25fps per stream. On the WF-RK3588-V1 the same silicon runs machine-vision defect classification at line speed on a factory floor. On the WF-RK3588-N3 it carries 16-channel AI surveillance analytics (person, vehicle, behaviour) on a fanless board. Each variant is tuned for its workload, but the silicon is the same, and that is what makes one supplier file cover nine deployment categories for Portugal buyers.

Can AndroidSBC handle CE, FCC, UKCA, RoHS, REACH and IEC 62368-1 paperwork for Portugal?

Answer: Yes, and the file travels with the goods rather than behind them. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated within the prior year. AndroidSBC will also advise on any Portugal-specific addition during quotation, which is the point at which the answer is still useful.

What are the MOQ and lead time for a first order on the WF-RK3588?

Answer: The entry point is 5,000 units per shipment, four weeks for samples and six weeks for production. A twelve-month framework agreement released monthly will bring the per-lot MOQ down, and AndroidSBC will accept a mixed order that draws several WF-RK3588 variants against a single contract.

Does AndroidSBC support custom Android ROM, custom Linux, or custom NPU model porting?

Answer: Yes, under NDA. ODM partners get custom Android ROM work including proprietary services and a custom launcher, Linux builds based on Ubuntu, Debian, Yocto or Buildroot, BSP ports for custom carrier boards, and NPU model porting through the Rockchip RKNN-Toolkit2 (quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet). The SDK and BSP source are released to the partner under the NDA, and AndroidSBC's engineering desk handles the port rather than handing over an unmodified vendor drop.

What about software updates and long-term support on the WF-RK3588?

Answer: Seven years minimum supply, with security patches maintained across the Android, Ubuntu LTS and Yocto firmware lines. Partners who deploy at scale can use the AndroidSBC OTA infrastructure to update field units and push new RKNN NPU model builds. For long-lifecycle programmes in machine vision, AI NVR, robotics or industrial control, the support term is written into the framework agreement at signature.

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

Answer: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.

How does AndroidSBC handle RMA or DOA replacements on the WF-RK3588?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-RK3588-R2 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit burn-in record means the failure report usually carries a root cause alongside the replacement, which is what a Portugal integrator running a production line actually needs.
