The Adafruit MagTag Starter Kit bundles everything you need to get started with the MagTag WiFi E-Ink display. The ESP32-S2-powered board features a 2.9" grayscale E-Ink screen that retains its image even when power is removed — perfect for low-power IoT dashboards, status boards, and information displays.

This kit includes a rechargeable LiPo battery for portable use (the MagTag draws just 250 µA in deep sleep for weeks of battery life), an acrylic mounting kit, and four magnetic feet so you can attach it to any metallic surface. Compatible with both Arduino and CircuitPython.
