I recently bought an Okdo Rock 5B 8GB.
If you look at the specs, it’s a “better” alternative then a RPI4:
– Faster CPU
– 2x HDMI output, supports 8K60p
– HDMI input that supports 4K60p
– SD/EMMC and M.2 2280 SSD support
– M.2 2230 for SATA / Wifi(6) / SDIO / PCM etc …
– Ethernet with support up to 2.5 Gbps
So, I’m running Debian on this board, and it “feels” more like a “desktop” machine, then a RPI4 does …
