i am waiting to see what dave might release on the low end side in the next few months. He is talking about a board that has fuses, leds, power distribution and a plugin for a beagle black SBC. This board may be able to do 16-48 strings of lights and be starting around ~$100 for 16 strings as a kit.
With the beagle black running fpp this new board can be added into my show easily.
First Software Dave is finishing the first pass of xLights 4 he then turns into Hardware Dave to look at the low end Beagle Black controller (~$100) and the High end Falcon-16 v2 (~$230-250).
Lots of controller choices this year. Holiday Coro board looks good also.
all of these controllers will work on xLights as a player or the FPP
