Hello
I purchased the following items:
Adafruit 16x8 LED Matrix Driver Backpack - HT16K33 Breakout - ID: 1427
Small 1.2" 8x8 Ultra Bright Red LED Matrix - BL-M12A881UR-11 ID: 455 X 2
I wanted to know how to wire the LED matrix to the 16x8 backpack. I am not sure which pins on the LED Matrix go to which pins on the backpack. The backpack is labeled with A0-A15 and C0-C7 but the LED Matrix itself does not have any labeling on it so I have no idea which pin is what.
Any help would be greatly appreciated.
Thank!

The datasheet shows the pinout and organization of the matrix:

Hello and thank you for the datasheet. That was helpful but I still do not know which pin is which on the physical component (LED Matrix) Obviously once I know that it should be easy to wire it to the backpack. Is there another diagram that shows this?

If you look at the side of the matrix with the part number printed on it, pin 1 will be on the left.
