A D-STAR hotspot. I've got a Zumspot which I use for DMR but decided to put my own one together for D-STAR. They'll work on a Zero but as soon as you start doing anything in the config, the CPU pegs at 100% and it really slows down. Even at idle, the CPU load reported by the OS is rarely below 1.50.@Feek what project you going to be doing with it? I was tempted to get another pi 4 to play with ubuntu 19.10.
I've ordered this HAT which is the same physical size as the 3A+ so it makes sense to use one.
