Potential All-in-One Single Board Computers

Btt manta M8P -Hardware wise it looks usable, they even put the spi pins right beside the rpi header. has mcu sd card also. uses cm4 footprint -mcu is stm32g0b1 ,currently untested, mbed supports a version of this chip so maybe -needs jumpers to spi

Fysetc Cheeta mix -hardware wise it looks fine, similar to their other boards, cm4 spi broken out on rpi header, uses cm4 footprint -mcu is stm32f401. should be fine, but i havent been able to get fysetc boards to work yet with remora wither their sd/spi setup. -needs jumpers from spi to spi

MKS SKIPR - hardware wise spi is broken out and there are 2 sd slots. has rk3328 -MCU is stm32f407, so well supported for remora. could work pretty easy but im having issues with another mks board re: sd card - hardware wise i like this one the best -needs jumpers

Mellow Gemini v2 -hardware wise I see an SOC spi broken out, so it looks usable. it looks like they might even have a direct line from mcu spi2 to soc spi0, via some switches I think they use this for automatic firmware updates, but we can use this for remora -MCU is stm32f405, so could probably work. -no wires needed possibly

Fysetc spider king. this one is pretty cool. -pretty good hardware, with a 26 pin rpi compatible pinout for connecting to uart and spi. -MCU is a socketed replaceable MCU, finally someone gets it. so far only the stm32f407 but others to come.
