This Wemos S2 Mini is a new version of the well-known Wemos D1 Mini. The S2 Mini is based on an ESP32-S2 chip, and has about 2x as many GPIO pins as the D1 Mini. The compact design of this module makes it an ideal development board to keep your project small. Because this module has the same form factor as the D1 Mini, most shields can also be used with this module. The Wemos S2 Mini is easy to program in Arduino, MicroPython or ESP-IDF.
