Unlike our LED matrix/segment backpacks, this breakout does not have holes for an existing LED module. Instead, we break out all 16 anodes and 8 cathodes as well as the I2C and power pins. You'll need to wire up the anodes and cathodes by checking out your matrix datasheet and lining up the pins. Wire up any matrix you want and use our handy library to write to the display however you wish. Note that the driver can turn LEDs on and off but does not have the ability to individually PWM dim them. This chip is rock solid, has & written for it and is easy to use.
The chip supports also reading a 3x13 keypad matrix but we do not have example code for it in our library, check the datasheet for more details about the keypad functionality.
