I have a lattepanda v1 on it’s way. $99 bucks for the 2GB RAM/32GB emmc version, but I bought the 4GB/64GB one. Seems to be about the same size as the CPI3.14 board. Sadly, the display connectors are incompatible. The lattepanda easily runs windows 10 (included) with a minimal cpu cooler. It pulls the same or less power as the A06. I might try to hack it into the devterm case for shits and giggles…
It even has an rpi co-proccessor and full rpi headers.
