{"title":"Adafruit MagTag - 2.9\" Grayscale E-Ink WiFi Display","handle":"adafruit-magtag-2-9-grayscale-e-ink-wifi-display","url":"/products/adafruit-magtag-2-9-grayscale-e-ink-wifi-display","description":"The Adafruit MagTag is a WiFi-connected E-Ink display board powered by the ESP32-S2. Its 2.9\" grayscale display retains its image even when power is removed, making it perfect for low-power IoT dashboards, status boards, and information displays that only need to update periodically.\n\nDesigned for low-power operation with built-in LiPo charging over USB-C, the MagTag draws just 250 µA in deep sleep — enough to run for weeks on a small battery. Four magnetic standoff feet (sold separately) let you mount it on any metallic surface like a fridge, shelf, or workbench.\n\nKey Features\n\n\nESP32-S2 Processor – 240 MHz Tensilica with native USB, 4 MB flash, and 2 MB PSRAM (WROVER module, FCC/CE certified)\n\n2.9\" Grayscale E-Ink Display – 296×128 pixels with 4 shades (white, light grey, dark grey, black); ~1 second refresh\n\nLow Power Design – 250 µA deep sleep with NeoPixels and amplifier disabled\n\nBuilt-in LiPo Charging – USB-C with battery connector for 350–420 mAh batteries\n\nFour NeoPixel RGB LEDs – Side-emitting LEDs to illuminate the display\n\nFour Buttons – Wake from deep sleep or select display modes\n\nLIS3DH Accelerometer – Detect display orientation\n\nSpeaker/Buzzer – Mini Class D amplifier on DAC for tones and lo-fi audio\n\nFront-Facing Light Sensor – For ambient light detection\n\nSTEMMA QT Port – Plug-and-play I2C for adding sensors and peripherals\n\nTwo STEMMA 3-Pin JST Connectors – For NeoPixels, speakers, servos, or relays\n\nOn/Off Switch – Plus boot and reset buttons\n\n\nIdeal For\n\nIoT dashboards and status displays (weather, calendar, quotes)\nLow-power information boards on battery\nFridge-mounted shopping lists or family message boards\nWiFi-connected sensor readout displays\n\n\nPackage Contents\n\n1× Adafruit MagTag (ESP32-S2 with 2.9\" E-Ink display)\n\n\n\nNote: Battery, magnetic feet, and STEMMA QT cables are sold separately. Compatible with both Arduino and CircuitPython.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14403,"title":"Default Title","sku":"AF-4800","price":72.73,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
