I’m using a Seeed XIAO C3
(really exciting board: cheap, has integrated battery charging circuit, great BLE/Wifi reception and it is also the smallest dev board around) (but no rgb)
You can see a couple of photos here

So far no reboot, (at least judging by the “uptime” counter on SYStoMQTT topic)
I’ll keep an eye on it and report here
