Radxa ROCK Pi E25 is a Rockchip RK3568 SBC, which is
based on the Radxa ROCK Pi CM3 IO core board.
It has the following features:
- MicroSD card socket, on board eMMC flash
- 2x 2.5GbE Realtek RTL8125B Ethernet transceiver
- 1x USB Type-C port (Power and Serial console)
- 1x USB 3.0 OTG port
- mini PCIe socket (USB or PCIe)
- ngff PCIe socket [USB (or SATA, not tested)]
- 1x User LED and 16x RGB LEDs
- 26-pin expansion header
