Adafruit Mini 8x8 LED Matrix w/I2C Backpack - Red IMU Sensors We've designed a backpack printed-circuit

We've designed a backpack printed-circuit board the fits on top of an Atmel ATmega168

A detailed explanation of the I²C interface on the VL53L1X can be found in its datasheet (1MB pdf)

The circuit board is laminated and sealed with a waterproof gasket and breathable composite waterproof glue so that the heat generated by the circuit board can be dissipated freely

The TReX blends RC

Adafruit Mini 8x8 LED Matrix w/I2C Backpack - Red IMU Sensors We've designed a backpack printed-circuitWhat's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display . Matrices like these are 'multiplexed' so to control 64 LEDs you need 16 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn't it be
