Adafruit Add-on kits for Raspberry Pi - Adafruit ADA1115, The Adafruit Blue & White 16x2 LCD+Keypad Kit for Raspberry Pi is an innovative solution for adding a display and user interface to your projects. This kit features a 16x2 character LCD with a blue and white display, complemented by a versatile Pi plate keypad with 4 directional buttons and a select button. It utilises only two I2C pins of a Raspberry Pi, preserving other GPIO pins for additional uses. (Even better, you don't really lose those two pins either, since you can stick I2C-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle.) The kit is ready for assembly, and includes buttons, chips, and other components that require soldering to the PCB. Assembly is straightforward and Python code is available for easy integration, making this kit ideal for creating stand-alone projects with a user-friendly interface. The kit ensures efficient use of GPIO
