{"title":"Adafruit I2C Controlled + Keypad Shield Kit for 16x2 LCD","handle":"adafruit-i2c-controlled-keypad-shield-kit-for-16x2-lcd","url":"/products/adafruit-i2c-controlled-keypad-shield-kit-for-16x2-lcd","description":"The Adafruit I²C Controlled + Keypad Shield Kit lets you drive a 16×2 character LCD and read 5 navigation buttons using only two I²C pins on your Arduino. This frees up the 9+ digital pins that a standard LCD connection would require, while still allowing other I²C devices to share the bus.\n\nThe shield includes 4 directional buttons plus a select button, making it ideal for standalone projects with their own user interface. It supports standard blue/white LCDs as well as RGB backlight LCDs, with the ability to switch between 8 backlight colours (red, yellow, green, teal, blue, violet, white, and off).\n\nKey Features\n\n\nI²C Control – Drive the LCD and read buttons using only 2 pins, leaving other pins free\n\n5 Navigation Buttons – 4 directional plus select, queryable through the Arduino library\n\nRGB Backlight Support – Control RGB backlight LEDs for 8 colour options\n\nShared I²C Bus – Connect additional I²C sensors, RTCs, and other devices alongside the shield\n\nLiquidCrystal Compatible Library – Drop-in replacement for the built-in Arduino LCD library\n\nUSA-Made PCB – High-quality shield with all components included\n\n\nIdeal For\n\nStandalone Arduino projects with user interface controls\nMenu-driven embedded systems\nSensor readout displays with navigation\nLearning I²C communication and LCD interfacing\n\n\nPackage Contents\n\n1× I²C LCD Shield PCB\n5× Navigation buttons\nHeader pins and all required components\n\n\n\nImportant: The 16×2 character LCD is NOT included. You will need to purchase a compatible 16×2 LCD separately. This kit has only been tested with Adafruit's own LCDs.\n\n\n\nNote: This is a kit that requires soldering — assembly takes approximately 30 minutes. Compatible with Arduino Uno, Duemilanove, Diecimila, and Mega R3. Earlier Mega boards require manual I²C wiring to pins 20 and 21. RGB backlight control is on/off per colour channel only (no PWM dimming).\n\n\nResources\n\nRGB LCD Shield Assembly and Usage Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14202,"title":"Default Title","sku":"AF-715","price":21.51,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
