Adafruit MagTag - 2.9" Grayscale E-Ink WiFi Display SF_Data Loggers and more in our CrickitThe Adafruit MagTag combines the new ESP32 S2 wireless module and a 2. 9" grayscale E Ink display to make a low power IoT display that can show data on its screen even when power is removed! The ESP32 S2 is great because it builds on the years of code and support for the ESP32 and also adds native USB support so you can use this board with Arduino or CircuitPython! We designed this board to be low power friendly with a spot for a 350 or 420 mAh
