Avalue RSC-3576J-3W-A100R Octa-Core Rockchip RK3576J 3.5″ Arm SBC with 12 to 24 V DC Input, Dual GbE and -40 to 85 °C

Roadside units, charging points and outdoor kiosks are taking on more local work: a touch interface, video, data logging and several network protocols on one board, in an enclosure that sees frost and summer heat. The RSC-3576J-3W-A100R is the build in the Avalue RSC-3576J series for that combination, an octa-core Rockchip RK3576J 3.5″ Arm SBC on a 146 x 102 mm board rated from -40 to 85 °C.

The Rockchip RK3576J pairs four Arm Cortex-A72 cores with four Cortex-A53 cores, so the interface and data processing can run on the larger cores while communications stay on the smaller ones. The RSC-3576J-3W-A100R carries 4 GB of LPDDR4 memory soldered to the board and 32 GB of eMMC, with an M.2 slot for an SSD. Avalue lists Android 14 and Debian 12 for the board.

Two GbE RJ45 ports on Realtek RTL8211FI-CG PHYs give separate field and uplink networks. Two RS-232 and two RS-485 ports sit on internal headers, and a CAN port on a terminal block takes field wiring directly. HDMI and LVDS run two displays together, with MIPI DSI sharing the LVDS interface. External USB covers one USB 3.0 and one USB 2.0 Type-A port and a USB OTG Type-C port, with four more USB 2.0 ports on internal headers for a touch controller, card reader or printer. A 4G modem and Wi-Fi with Bluetooth are available as options, and audio includes a headphone jack.

Power is 12 to 24 V DC on a barrel connector. Avalue tests the board to IEC 60068-2-64 random vibration at 1.5 Grms in operation and ISTA 2A drop, and the RSC-3576J-3W-A100R carries CE and FCC compliance with 10 to 95% non-condensing humidity. It suits outdoor signage and kiosks, EV charging, rail and road equipment, energy monitoring and factory automation that needs eight cores in a compact enclosure.
