Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731
The Adafruit IS31FL3731 breakout is a charlieplexed PWM LED matrix driver that controls a 16×9 grid of individually dimmable LEDs over I2C. Each of the 144 LEDs can be set to any brightness level with 8-bit (256-level) PWM — no complex wiring or constant signal sending required. The IS31FL3731 o...
Adafruit TCA8418 Keypad Matrix and GPIO Expander Breakout
The Adafruit TCA8418 Keypad Matrix and GPIO Expander Breakout is a versatile I2C GPIO expander and keypad matrix driver. With 18 I/O pins (10 columns and 8 rows), it can manage up to 80 switches in a matrix configuration or serve as individual GPIO inputs and outputs. Whether you need more butto...
16x8 1.2 LED Matrix + Backpack - Ultra Bright Square Amber LEDs
A 16×8 LED matrix backpack kit featuring two ultra-bright 1.2" amber 8×8 square LED matrices on a single I2C-controlled driver board. The square pixel shape creates a seamless, uniform look compared to round LEDs. The HT16K33 chip handles all the multiplexing, so you only need two I2C pins to con...
