Summary
This circuit integrates an ESP32C3 Supermini microcontroller with a LORA_RA02 module for LoRa communication and a DHT11 Sensor V2 for measuring temperature and humidity. The ESP32C3 Supermini is responsible for controlling the LoRa module and reading data from the DHT11 sensor. The circuit is designed to operate on a 3.3V power supply, which is common to all components, and a ground connection is shared across the circuit.
