TL;DR: RK3568 SD Card Slot POS Terminal Board for POS Terminal
AndroidSBC OEM partnership announcement extending WF-S board availability serving Riga, Latvia. The WF-S3504 self-service checkout Android motherboard spans the industrial fanless self-checkout SBC 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, HDMI 4K + dual LVDS, and Android 13 / Linux firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-S family from the Longgang source factory in Shenzhen to Riga and Latvia 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
The AndroidSBC WF-S family is a Wanlin Manufacturing Group OEM and ODM platform built around two silicon tiers, Rockchip RK3568 for premium self-checkout, dual-screen POS, and industrial kiosk use cases, and Allwinner A133 for entry-level POS, F&B ordering kiosks, and locker terminals. Each WF-S motherboard ships from the Wanlin Longgang factory with the Android 10 to Android 14 firmware, payment peripheral drivers, and CE / FCC / UKCA / RoHS paperwork ready for Latvia importers. For Latvia 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-S3504 Technical Specifications
| Parameter | AndroidSBC WF-S3504 (industrial fanless self-checkout SBC) | Industry Average |

For Latvia importers sourcing the WF-S family, the WF-S3504-A variant is the typical configuration for the industrial fanless kiosk SBC use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Checkout Android Motherboards for Latvia Buyers
Procurement teams in Latvia typically ask three questions when evaluating Chinese self-service checkout Android motherboard factories: can the factory lock the Rockchip RK3568 or Allwinner A133 silicon, can it bundle payment-peripheral drivers, and can it deliver CE / FCC / RoHS paperwork for Latvia customs. AndroidSBC, a Wanlin Manufacturing Group export brand, addresses all three through the WF-S self-service checkout Android motherboard family.
SPRK conformity plus CE marking with SPRK radio interface notification plus Port of Hamburg routing is the standard Latvia compliance pathway for self-checkout Android motherboards with WiFi 6 or Bluetooth 5.0 modules. The WF-S self-service checkout Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand, bundles the paperwork into the Shenzhen source factory shipment. Wanlin Longgang released the 64000-unit WF-S self-service checkout Android motherboard order for Riga, Latvia on September 14, 2026, after burn-in on the 5th lot.
Competitive Comparison: WF-S3504 vs Competing Self-Service Checkout Android Boards
For self-service checkout Android motherboard procurement in Latvia, four technical comparisons matter: silicon tier, driver support, firmware baseline, and certification paperwork. AndroidSBC, a Wanlin Manufacturing Group export brand, scores on all four against the WF-S family:
- vs single-platform 28nm boards: the WF-S family covers both Rockchip RK3568 8nm premium tier and Allwinner A133 22nm entry tier from one Shenzhen source factory.
- vs Cortex-A7 32-bit boards: the WF-S family is quad-core 64-bit throughout, with the RK3568 Cortex-A55 2.0GHz and the A133 Cortex-A53 1.6GHz both on the ARMv8 instruction set.
- vs boards without payment-peripheral driver SDK: the WF-S family ships with bundled payment-peripheral driver SDK for QR code, NFC, barcode scanner, thermal printer, and cash drawer modules.
- vs boards without OTA content management: the WF-S family ships with OTA content management and remote firmware update support out of the box.
