I just learned about Meshtastic from Andreas Spiess’ video This is the kind of thing I’ve been looking for ages.
I bought a couple of “2Pcs TTGO LORA32 V2.0” modules about a year ago. I’ve not used them for anything until now. I managed to flash them with Meshtastic and they appear to work. The “2Pcs TTGO LORA32 V2.0 listing” says that the working voltage is: 1.8~3.7v. Can I connect a 1S LiPo battery (4.2V) to the battery terminals or is that going to blow the module up?
