SX1276 LoRa Transceiver Module 868MHz 915MHz IOT 0.96inch OLED Display ESP32 Wifi Bluetooth Development Board + Antenna + JST Battery Connector for Arduino Nodemcu Geekstory

I wanted to use these for the Meshtastic project. I've bought them before and know how to load custom firmware. But this set I cannot get the screens to work. Seems like there is a bit of an issue with the production of these boards, some work great, others have issues.

I am using this for a weather tracking project. I bought two units, one sits outside in the weather station with temperature and wind sensors. The other sits inside to provide me the display data collected outside. This is my first project using LoRa for communication and OLED for display, and I immediately love both. The tiny package makes it so easy to fit into a compact unit, while displaying dense data and a variety of communication options. The picture shows the default firmware, before I setup the connection over wireless. In the weather station, I have the two units configured for point-to-point at 915 MHz since I am in North America. Just a really cool device.

These work well
