I am newly interested in Compute Module style SBCs after I bought a one to toy around with. I was surprised to learn that the PCBs that interface to them are open specs and I can probably build myself more custom PCB solutions to match different form factors instead of being stuck with a bulky normal Raspberry Pi.

I was pleased to learn that Radxa and Orange Pi have compatible similar boards.

I have wanted to see more RISC SBCs so I may toy with these but I rather wait for the software support to get much richer.
