TL;DR: 1-3 Days Sample Delivery POS

AndroidSBC cross-border logistics briefing serving Colombo, Sri Lanka. The WF-S3500 self-service checkout Android motherboard spans the dual-screen self-service checkout terminal and eight sister models (WF-S3500 through WF-A1303), all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the Mali-G52 2EE GPU and 1 TOPS NPU, dual LVDS + HDMI 4K@60fps, and Android 13 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-S family from the Longgang source factory in Shenzhen to Colombo and Sri Lanka importers who run self-checkout, POS terminal, kiosk, dual-screen cashier, smart retail, and unmanned-store programs.

About AndroidSBC and the Self-Service Checkout Android Motherboard Family

AndroidSBC, the Wanlin Manufacturing Group export brand, packages the WF-S self-service checkout Android motherboard family as a direct-from-source alternative to franchise-tier brand boards. Colombo and Sri Lanka buyers can source Rockchip RK3568 8nm and Allwinner A133 22nm boards from a single Shenzhen factory, with CE / FCC / RoHS paperwork and 1-3 day sample delivery handled by AndroidSBC. For Sri Lanka specifically, the WF-S family streamlines the supermarket self-checkout, F&B ordering kiosk, and unattended-store segments by offering a single source factory for both the Rockchip RK3568 8nm premium tier and the Allwinner A133 22nm entry tier.

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. For Sri Lanka importers sourcing the WF-S family, the WF-S3500-A variant is the typical configuration for the dual-screen self-checkout kiosk use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Checkout Android Motherboards for Sri Lanka Buyers

For Sri Lanka retail and hospitality chains, the biggest sourcing friction on self-service checkout Android motherboards has been the gap between factory-quoted Rockchip RK3568 8nm performance and factory-shipped Rockchip RK3566 28nm silicon. The WF-S self-service checkout Android motherboard family from AndroidSBC locks the Rockchip RK3568 8nm BOM and the Allwinner A133 22nm entry-tier BOM into a single source factory contract.

For Colombo and Sri Lanka, the TRCSL / SLSI conformity plus TRCSL type approval with SLSI import conformity is the typical import compliance anchor for self-service checkout Android motherboards with WiFi 6, Bluetooth 5.0, or 4G LTE modules. AndroidSBC ships the WF-S family with the paperwork bundled. 175600-unit WF-S self-service checkout Android motherboard production lot cleared burn-in for Colombo, Sri Lanka on September 14, 2026 and is en route via the Colombo - Singapore lane.

Competitive Comparison: WF-S3500 vs Competing Self-Service Checkout Android Boards
