Firefly Core-3562JQ Rockchip RK3562J industrial SoM works in the -40 to +85°C temperature range

Firefly Core-3562JQ is a system-on-module based on Rockchip RK3562J SoC – the industrial-grade version of the Rockchip RK3562 quad-core Cortex-A53 Tablet SoC – designed to operate in the -40 to 85°C industrial temperature range and suitable for digital signage, industrial control systems, industrial PLCs, energy data concentrators, smart healthcare, self-service terminals, and more.

The CPU module features up to 8GB RAM, 64GB flash, and a Rockchip RK809-5A PMIC, plus three 80-pin board-to-board connectors exposing video output and input interfaces, audio (SPDIF, PDM, I2S) interfaces, networking (GbE and Fast Ethernet), various USB interface, a 1-lane PCIe 2.1 interface, and more.

Firefly Core-3562JQ module board-to-board connectors

Firefly will provide Ubuntu, Debian, and Linux Buildroot+Qt images for its Rockchip RK3562J CPU module, but that’s about all the information we have on the software side as the documentation page is currently empty. The Core-3562J SoM looks to be an entry-level/cost-down version of the Core-3568JQ system-on-module found in the Firefly ITX-3568JQ mini-ITX motherboard, but it won’t be pin-to-pin compatible dues to the different number and placement of the board-to-board connectors.

Firefly did not provide availability and pricing information for the Core-3568JQ industrial SoM, and I found out about it in the video below. The product page may also have a few more details.

The guaranteed operating temperature of Samsung DRAM and eMMC is -25°C ~ 85°C, but I don’t know what basis they use to advertise the operating temperature of SoM as -40°C ~ 85°C.

I already looked into the part numbers on the first picture and they are NOT industrial/automotive grade at all.
I hope the SoMs they actually sell don’t have commercial grade memory chips.
