The company mentions that the RK3576 module and SBC support Android 14 and Debian 12, both running on a Linux 6.1.99 kernel with U-Boot 2017.09 as the bootloader. It includes drivers for eMMC 5.1, HDMI 2.1 (4K), DP-to-HDMI, HDMI-to-MIPI (TC358749XBG), WiFi 5, Bluetooth 5.0, and 4G LTE modules. Development tools include SecureCRT, ADB, and AndroidTool.exe for debugging and firmware upgrades, with cross-compilation supported on Ubuntu 22.04 environments. More information can be found on the software section in the product page linked below.
The company also mentions that it’s easily upgradable, but if you are doing it yourself, you will need a hot air soldering station and other tools to properly replace the SoM.
We have previously written about other Rockchip SBCs and dev boards from Broadcon, like the Boardcon Compact3588S SBC, the Boardcon SBC3576 SBC with a MINI3576 system-on-module with B2B connector, and the Boardcon EM3568-AV CAM board. We also covered another SBC based on the CM3576 SoM: the EM3576 SBC with a unique design comprised of 12x analog camera BNC connectors.
The company showcases an enclosure for the SBC, but does not mention anything about it.
Boardcon did not provide any pricing information about the SBC, so you would have to contact them for details. More information can be found on the product page and the press release.
