Avalue RSC-3568J-6W-A104R Rockchip RK3568J 3.5″ SBC with 12 to 24 V DC Input, Dual GbE and Extended Temperature

A board inside an EV charger, a roadside cabinet or a trackside display has no air conditioning and no easy access for a fan replacement. The RSC-3568J-6W-A104R is the build in the Avalue RSC-3568J series for that job, a Rockchip RK3568J 3.5″ SBC on a 146 x 101 mm board that runs fanless from -40 to 85 °C, with dual GbE, five serial ports and two CAN ports.

The Rockchip RK3568J has four Arm Cortex-A55 cores and a Mali-G52 GPU supporting OpenGL ES 3.2, Vulkan 1.1 and OpenCL 2.0, which suits a signage player, a charging-point interface or a protocol gateway. The RSC-3568J-6W-A104R carries 4 GB of LPDDR4 memory soldered to the board, 64 GB of eMMC and a microSD slot, and Avalue lists Android 13 and Debian 11 as supported operating systems.

Two GbE RJ45 ports on Realtek RTL8211FDI PHYs separate a field network from the uplink. Serial covers one RS-232/422/485 port on a DB9, one RS-232/422/485 header and three RS-232 headers, with two CAN ports and a 16-bit GPIO header beside them. Displays connect through HDMI at up to 4096 x 2160, LVDS and eDP, with dual display support. An M.2 B-key 3042 slot takes a SATA SSD or a 4G module with the nano SIM socket, and an M.2 E-key 2230 slot takes a Wi-Fi and Bluetooth module. USB covers two USB 3.0 Type-A ports, one with OTG, plus two internal USB 2.0 headers.

Power is 12 to 24 V DC on a lockable DC jack or a 4-pin wafer, with AT power-on when input is applied, so the board restarts on its own after a supply interruption. Avalue tests it to IEC 60068-2-64 random vibration and ISTA 2A drop, and it carries CE and FCC compliance with 10 to 95% non-condensing humidity. The RSC-3568J-6W-A104R suits outdoor signage, EV charging, transport ticketing, energy monitoring and machine controllers.
