Adafruit TCA8418 Keypad Matrix and GPIO Expander Breakout - a cute and powerful I2C GPIO expander and keypad matrix driver! This chip is quite fancy, with the ability to act as your I2C multi-tool for handling keypads, buttons or LEDs. This board uses a 4-pin Sparkfun Qwiic-compatible connector called STEMMA QT, which allows the sensor to communicate over I2C without soldering.
