Avalue RSC-3576J Rockchip RK3576J 3.5" Arm SBCs with 12 to 24 V DC Input, Dual GbE and -40 to 85 °C

Equipment that runs outdoors or beside heavy machinery increasingly needs more processing than a quad-core Arm board offers, whether for a richer HMI, local data processing or several protocol stacks at once. The Avalue RSC-3576J series is a family of Rockchip RK3576J 3.5″ Arm SBCs that brings eight cores to a 146 x 102 mm board rated from -40 to 85 °C.

The Rockchip RK3576J combines four Arm Cortex-A72 cores with four Cortex-A53 cores, so demanding tasks run on the larger cores while background services stay on the efficient ones. Memory is 4 GB of LPDDR4 soldered to the board, with 32 GB of eMMC for the operating system and an M.2 slot for an SSD when logs, media or a local database need more room. Avalue lists Android 14 and Debian 12 for the series.

Two GbE RJ45 ports use Realtek RTL8211FI-CG PHYs. Serial covers two RS-232 and two RS-485 ports on internal headers, and a CAN port sits on a terminal block for field wiring. HDMI and LVDS run two displays together, with MIPI DSI sharing the LVDS interface as a build option. USB is generous for the size: one USB 3.0 and one USB 2.0 Type-A port, a USB OTG Type-C port and four internal USB 2.0 headers. A 4G modem and Wi-Fi with Bluetooth are available as options, and audio covers a headphone jack and a speaker header. When fitted, Wi-Fi is 2T2R 802.11ax with Bluetooth 5.0. A backlight connector and an I2C connector on FPC support panel builds.

The range is one build: RSC-3576J-3W-A100R, with 4 GB of memory, 32 GB of eMMC and the full -40 to 85 °C rating, so one part number covers indoor and outdoor installs.

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 it carries CE and FCC compliance with 10 to 95% non-condensing humidity. The RSC-3576J series suits outdoor kiosks and signage, EV charging, rail and road equipment, energy monitoring and factory automation that needs extra cores in a compact enclosure. The datasheet also lists sine and package vibration tests under IEC 60068-2-6 and IEC 60068-2-64.
