About AndroidSBC and the Self-Service Checkout Android Motherboard Family

Wanlin Group is the parent of AndroidSBC and the source factory for the WF-S self-service checkout Android motherboard family. The WF-S line is a nine-variant range of Rockchip RK3568 and Allwinner A133 boards designed for unattended retail, supermarket self-checkout, restaurant ordering kiosks, smart locker terminals, and dual-screen cashier programs. For Portugal, the WF-S family gives retail, hospitality, and F&B integrators a single Shenzhen source factory for Rockchip RK3568 self-checkout motherboards and Allwinner A133 entry-level POS boards, both with CE / FCC / RoHS paperwork bundled.

WF-S3500 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-S3500 (dual-screen self-service checkout terminal) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps.
