The Wemos D1 R32 is an Arduino Uno form factor ESP32 dev board. With a clock speed up to 240Mhz and one core dedicated to wireless functions, it is MUCH faster than the ESP8266. Perfect for arduino, NODEMCU or micropython projects that need more ‘oomph!’.
NOTE: This is a 3.3V device. So may not work with all arduino shields.
