EXT-2.5GE-RK3588-RT is a quad 2.5GbE Ethernet expansion board for ROC-RK3588-RT SBC
In a recent article, we covered the ROC-RK3588-RT SBC, one of its main features was its three ethernet ports: one 2.5GbE and the other two standard ethernet ports. This setup made this board ideal for routers and firewalls. To enhance its capabilities, Firefly recently launched the EXT-2.5GE-RK3588-RT, a 2.5GbE Ethernet Expansion Board, which adds four more 2.5GbE ports to the ROC-RK3588-RT Rockchip RK3588 SBC. We’ve previously covered many SBCs, mini PCs, and motherboards from Firefly, such as their Rockchip RK3588 SBCs with 32GB RAM, the Firefly AIO-1684XQ motherboard, and the Firefly Station P3D mini PC. Feel free to check them out if you’re interested. While searching, I found limited documentation, but upon closer inspection, I discovered that the board uses the RTL8125BG IC for Ethernet control and the PI6C557-05 IC as a spectrum clock generator. There is also some kind of PMIC on the board recognizable by the big inductor, […]
