So versatile
These boards are just so neat and versatile.... the combination of ESP32, Lora, GPS and battery management on a single board fits in with so many projects.I have a few minor criticisms though:1. The onboard wifi antenna is really easy to break off the board (although there is a socket for an external antenna - to use it you do have to move a surface mount resistor).2. There is no way of measuring the battery voltage from the CPU3. It's really difficult to find schematics for all the various versions of the board, so sometimes you're left guessing what's actually connected where.None of these stop me buying more of these boards though - they're just so neat!

Somewhat difficult to program
It’s a very nice board however uploading compiled code is a bit hit and miss. I’ve had success with a Linux mint intel based computer with Visual Studio and the PlatformIO plug in with the Espressive C compiler. I had no success at all with a Raspberry Pi

Screen is easy to break
I managed to break the screen on mine by dropping it. I have quite a few similar boards and this is the only one that's broken so far.
