About AndroidSBC and the Self-Service Checkout Android Motherboard Family

The WF-S self-service checkout Android motherboard family is AndroidSBC, a Wanlin Manufacturing Group brand designed for global retail and F&B integrators. Each WF-S motherboard is built on either the Rockchip RK3568 8nm platform or the Allwinner A133 22nm platform, runs Android 10 to Android 14, and is delivered with payment-peripheral drivers, OTA content management, and CE / FCC / RoHS certification files. For United States in particular, retail chains, F&B operators, and unattended-store program managers can buy Rockchip RK3568 self-checkout boards and Allwinner A133 POS boards from one Shenzhen source factory under a single framework agreement.

WF-S3501 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-S3501 (15.6-inch all-in-one POS 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. For United States importers sourcing the WF-S family, the WF-S3501-A variant is the typical configuration for the 15.6-inch countertop POS terminal use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Checkout Android Motherboards for United States Buyers

Retail and F&B integrators in United States frequently hit a familiar wall: their Chinese factory sources either Rockchip RK3568 8nm boards at premium-tier pricing or Allwinner A133 22nm boards at entry-tier pricing, but rarely both from a single source factory. The WF-S self-service checkout Android motherboard family from AndroidSBC ships both tiers from the Wanlin Longgang facility, with shared firmware, shared CE / FCC / RoHS paperwork, and a 1-3 day sample lead.

For United States integrators, the FCC / UL conformity plus FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing is the typical compliance anchor for self-checkout Android motherboards shipping with WiFi 6 or Bluetooth 5.0 modules. AndroidSBC, a Wanlin Manufacturing Group export brand, ships the WF-S family with the FCC / UL paperwork bundled into the Port of Los Angeles shipment. Wanlin Longgang SMT line released a 163400-unit WF-S self-service checkout Android motherboard lot for Memphis, United States on September 14, 2026, the 4th lot on the WF-S line.
