Thanks @mascot1579 , this is interesting.
I am using the AirGradient PCB, so rewiring pins isn’t really an option (at least not without creating some frankenboard with random wires on top…). On top of that I’ve found out the hard way that the pixels I’m using aren’t happy on any pin other than RX/GPIO3.
Sounds like upgrading to ESP32 is the path of least resistance to fix the reboot issue. ESP8266 D1 mini and ESP32 C3 mini are the same cost, so assuming the C3 works (which I believe it will based on other forum posts (forum dot airgradient dot com /t/new-wemos-board/251/16 – incorrectly flagged as spam ) there isn’t much reason not to use the much more performant new hardware.
