{"title":"Adafruit Capacitive Touch HAT for Raspberry Pi - Mini Kit [MPR121]","handle":"adafruit-capacitive-touch-hat-for-raspberry-pi-mini-kit-mpr121","url":"/products/adafruit-capacitive-touch-hat-for-raspberry-pi-mini-kit-mpr121","description":"The Adafruit Capacitive Touch HAT adds 12 capacitive touch sensors to your Raspberry Pi using the MPR121 touch controller over I2C. Each sensor has a figure-8 hole designed for alligator clip connections — attach clips to the HAT and the other end to anything conductive (metal, fruit, vegetables, or water-filled objects) to create touch-reactive projects.\n\nThe included Python library makes it straightforward to detect touches, convert them into keyboard keypresses, or trigger audio playback. No soldering is needed for the touch connections themselves — just clip and go. For permanent installations, solder pads are also available.\n\nKey Features\n\n\n12 Capacitive Touch Sensors – MPR121 controller with I2C interface\n\nFigure-8 Alligator Clip Holes – Easy grip connections for each sensor pad\n\nPython Library – Detect touches, generate keypresses, or play audio per sensor\n\nHAT Form Factor – Plugs directly onto the Raspberry Pi 40-pin GPIO header\n\nSolder Pads – Available for permanent, slimmer connections\n\n\nCompatibility\n\nRaspberry Pi Model A+, B+, Pi 2, Pi 3, Pi 4 (with included 2×20 header)\nRaspberry Pi Model A or B (requires a 2×13 extra-tall header, not included)\n\n\nIdeal For\n\nInteractive touch installations\nFruit and vegetable keyboards/drums\nTouch-activated audio players\nEducational projects and exhibits\n\n\n\nImportant: This kit does not include a Raspberry Pi, alligator clips, speaker, or fruit. Alligator clips are recommended for connecting to touch objects.\n\n\nPackage Contents\n\n1× Adafruit Capacitive Touch HAT (MPR121)\n1× 2×20 socket header (requires soldering to the HAT)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9247,"title":"Default Title","sku":"AF-2340","price":30.83,"on_sale":false,"in_stock":true,"available_quantity":71,"option1":"Default Title"}]}
