back to meshtastic radios

Heltec V3:




These are very much "entry-level" radios, with no GPS, limited sensors, small display, and a power-hungry CPU.

I was given one about the time I decided to get into LoRa, and have since bought four more during the Black
Friday sales on Ali, for about $24/pair, plus a few bucks more for cases.

The common little white-and-green cases are intended for use with the included "spring" antenna, and so will
require a little drilling to use an external antenna.
