As part of the 'Express' series of boards, the Metro M0 Express is designed for use with CircuitPython. The tests were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. In this tutorial we will show how to build DS18B20 and ESP8266 temperature sensor without Arduino.
