Cool Pi CM5 evaluation board features Rockchip RK3588/RK3588J system-on-module

Cool Pi CM5 is a system-on-module based on Rockchip RK3588 or RK3588J (industrial temperature range) octa-core Arm Cortex-A76/A55 processor with up to 32GB RAM, 256GB eMMC flash, offered with a development board with dual GbE, two 8K HDMI 2.1 ports, a PCIe 3.0 x2 slot, M.2 NVMe and SATA storage, and more…

At the end of last year, we wrote about the Cool Pi 4 as a much faster alternative to Raspberry Pi 4 SBC, and the company has now launched a Raspberry Pi Compute Module 4 and Radxa CM5 alternative with the Cool Pi CM5 MXM 3.0 system-on-module that they offer along with a feature-rich evaluation board (EVB).

Cool Pi CM5 Rockchip RK3588 system on moduleThe Cool Pi CM5 EVB (RCP-CM5-EVB-2GNORK3588) is only offered with the commercial-grade CM5 module with 8GB RAM and 64GB flash, but the system-on-module itself is customizable and can be produced to be industrial grade with the Rockchip RK3588J processor.

Just like the Cool Pi 4 Model B, the Cool Pi CM5 SoM and EVB can run Android 12, Ubuntu, and Debian operating systems with images and more technical details provided in the Wiki, and support offered in a bilingual (Chinese/English) forum. The board has a fanless design with cooling achieved via a heat spreader placed underneath the board in direct contact with the Rockchip RK3588 processor.
