As someone that’s used a pile of Heltec Lora V3: they’re fragile pieces of overpriced shit. I’ve kept buying them as they’ve kept failing and I think I’ve purchased about a dozen in order to keep 2 devices alive, and the latest two are only a few weeks old. I’ve had a brand new one just stop working as I’ve programmed it for the first time, and I handle these things with an ESD strap on because I think they’re just really poorly protected.

I’m porting my project (a solar pump with radio linked trough float) to eByte e32s and a standard ESP32 because I’m tired of having these things crater if I look at them sideways.
