User Manual

Pins R1, G1 and B1 (labeled R0, B0 and G0 on some
matrices) deliver data to the top half of the display.
On the Arduino Uno and Adafruit Metro (328, M0 or
M4) boards, connect these to digital pins 2, 3 and 4.
On Arduino Mega, connect to pins 24, 25 and 26.
Lower RGB Data
Pins R2, G2 and B2 (labeled R1, G1 and B1 on some
matrices) deliver data to the bottom half of the display.
These connect to the next three Arduino pins…
On Arduino Uno and Adafruit Metros, that’s pins 5, 6
and 7.
On Arduino Mega, pins 27, 28 and 29.
