Forlinx OK3572-C
The OK3572-C is Forlinx’s development board for its FET3572-C system-on-module, a 68 × 50 mm module with four 100-pin board-to-board connectors. The industrial FET3572J-C module uses the RK3572J and runs from -40 °C to 85 °C. Forlinx gives customers a Linux 6.12 BSP with Forlinx Desktop 24.04, Debian 13 and Android 16. At launch these images were marked R&D.
