LILYGO LORA32 T-Beam ESP32 SoftRF Development Board WiFi BLE CH9102F Chip TTGO OLED Module

These units do work on Meshtastic (make sure you order the right one if it is the way you go or you will need to reflash it). However, they are cheap and Lord forbid if you want to put it in some type of case or before you get it n the case something brushes up against the cheaply soldered on components. Person setup for got bottom switch barely tangled on sweater, fell off board didn't even pull on it. The only reason I am ordering a 2nd is because the person who wanted me to get this setup for them is adamant this is what they wanted. I prefer my Wisblock stuff to this by leaps and bounds.

Biggest issue is lack of good documentation. It comes with zero documentation. A link to GitHub is about all you get. I did have an issue that I contacted their support with and they responded with more or less the right answer after several days. I had already figured out a solution from another GitHub site several days before getting the response. Which would have been unintelligible had I not already figured out the solution.The pins for hooking up the OLED are reversed from other vendors.Packaging is great. So far the only boards that have failed were due to my mistakesThe GPS has a tendency to stop sending data on the serial interface. This may require a reset using the SPI interface.

One worked, one didn't. I ordered a replacement that never showed up! Disappointed in the customer service

I used these for a tracker project that I built. After soldering the display, I was able to upload custom firmware with a freely downloadable tool via the board's USB port. The display was very handy for confirming the firmware was operating afterwards.

This worked perfectly for using in a meshtastic network. Just assemble, attach the antenna, flash the software to the latest Meshtastic and off you go. I do recommend getting a better ceramic GPS antenna. The one that comes with it works, just not inside most 3D printed cases out there. Same type ceramic GPS antenna, just the square one. If you are using Meshtastic you will know how to find the right one using their site set up files and FAQ. The included one is fine if you want it mounted outside the case open to the sky. The square ones sold here work great if you want it inside a 3D printed case made for the square antenna to be protected on the inside.
