This repository accompanies a large project centered around the small ESP32-H2 Super Mini development board. It consists of several sub-projects that deal with the topics SHT41 sensor, MAX17043 battery measuring device, LoRa module, e-paper display and onboard LEDs. The end result is a LoRa transmitter that can transmit data over long distances.
