A133 RS232/RS485 Multi-Serial POS Board Commercial Grade, WF-C3603, AndroidSBC, Colombo

TL;DR: A133 RS232/RS485 Multi-Serial POS Board Commercial Grade

AndroidSBC benchmark desk: WF-C RK3568 boards measured against entry-tier A133 boards serving Colombo, Sri Lanka. The WF-C3603 smart checkout counter Android motherboard spans the face-payment smart checkout counter terminal and eight sister models (WF-C3600 through WF-A1313), 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 HDMI 4K plus LVDS, and Android 14 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-C family from the Longgang source factory in Shenzhen to Colombo and Sri Lanka importers who run smart checkout counter, POS terminal, kiosk, dual-screen cashier, smart retail, and unmanned-store programs.

About AndroidSBC and the Smart Checkout Counter Android Motherboard Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group with more than a decade of OEM and ODM work on Rockchip and Allwinner platforms. The smart checkout counter Android motherboard family covered here is the WF-C line, nine models built on the Rockchip RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the Mali-G52 GPU and 1 TOPS NPU, and on the Allwinner A133 quad-core ARM Cortex-A53 1.6GHz SoC with the PowerVR GE8300 GPU. The Wanlin Longgang plant in Shenzhen builds the WF-C family for checkout counter, POS terminal, kiosk, dual-screen cashier and unmanned-store programmes that Colombo and Sri Lanka buyers bring to the table. For Sri Lanka in particular, retail chains, F and B operators and unmanned-store programme managers can buy Rockchip RK3568 checkout counter boards and Allwinner A133 cashier boards from one Shenzhen factory under a single framework agreement.

WF-C3603 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3603 (face-payment smart checkout counter 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-C family, the WF-C3603-A variant is the typical configuration for the face-payment checkout terminal use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Smart Checkout Counter Android Motherboards for Sri Lanka Buyers

Retail and F and B integrators in Sri Lanka keep hitting the same wall: their Chinese supplier offers either Rockchip RK3568 8nm boards at premium-tier pricing or Allwinner A133 22nm boards at entry-tier pricing, but rarely both from one factory. The WF-C family ships both tiers out of Wanlin Longgang with shared firmware, shared CE / FCC / RoHS files and a 1-3 day sample lead.

For Colombo importers, TRCSL / SLSI radio interface registration plus TRCSL type approval with SLSI import conformity is the normal pathway for smart checkout counter Android motherboards with WiFi 6 or 4G LTE. AndroidSBC, a Wanlin Manufacturing Group export brand, ships the WF-C family with the TRCSL / SLSI files included. Wanlin Longgang SMT released a 129900-unit WF-C smart checkout counter Android motherboard lot for Colombo, Sri Lanka on September 15, 2026, the 3rd lot on the WF-C line.

Competitive Comparison: WF-C3603 vs Competing Smart Checkout Counter Android Boards

When Sri Lanka integrators benchmark the WF-C family against competing Chinese boards, the comparison usually lands on four points. AndroidSBC addresses each:

• vs single-platform 28nm boards: the WF-C family covers both the Rockchip RK3568 8nm premium tier and the Allwinner A133 22nm entry tier out of one Shenzhen source factory.
• vs Cortex-A7 32-bit boards: the WF-C family is quad-core 64-bit throughout, with the RK3568 Cortex-A55 2.0GHz and the A133 Cortex-A53 1.6GHz both on ARMv8.
• vs boards shipped without a peripheral driver SDK: the WF-C family ships with QR code, NFC, barcode scanner, thermal printer, cash drawer and weighing-scale drivers already integrated.
• vs boards without remote fleet tools: the WF-C family ships with OTA content management, remote firmware update and kiosk-mode lockdown out of the box.

Global Smart Checkout Counter / POS Terminal / Kiosk Market Trends

MarketsandMarkets sizes the POS terminal hardware market at USD 58.4 billion in 2025 with a 9.7% CAGR to 2030 (MarketsandMarkets, POS Terminal Market Forecast, 2025-2030), and Sri Lanka buyers are reading that curve before committing to the face-payment smart checkout counter terminal category. In Colombo, the supermarket counter, F and B counter, retail counter and dual-screen cashier segments are converging on three AndroidSBC priority areas:

• Supermarket and convenience-store checkout lanes: WF-C3603 is the usual pick for chain-store procurement.
• F and B ordering counters and unmanned stores: WF-C3603 plus the entry-tier WF-A1312 sister SKUs form the F and B ordering ladder.
• Dual-screen cashier desks and smart retail payment: WF-C3603 plus the dual-LVDS and dual-HDMI sister SKUs cover the dual-screen segment.

For Sri Lanka integrators, those three segments carry most of the smart checkout counter Android motherboard volume for 2025 and 2026. AndroidSBC, a Wanlin Manufacturing Group export brand, ships the WF-C family on a 1-3 day sample lead and a 15-30 day mass-production lead so Colombo buyers can keep pace.
