R1
Upper-half red channel data input on the matrix input connector; Adafruit names R1/G1/B1 as RGB data channels, with some panels relabelled R0/G0/B0 but functionally equivalent.
Type · Signal
G1
Upper-half green channel data input on the matrix input connector; Adafruit notes label variants and colour-channel swaps on some panel batches.

Type · Signal
CLK
Clock input; Adafruit states CLK is one of the signals that must be connected to the matrix input connector.
Type · Signal
LATSTB
Latch/strobe input; Adafruit notes LAT may be labelled STB on some panel variants.
Type · Signal
OE
Output-enable input on the matrix input connector.
Type · Signal
5V
Panel power input; this 32x32 RGB LED matrix family is powered from 5V supply connections.
Type · PowerVoltage · 5V panel power input.
GND
Ground return for signal reference and panel power; Adafruit notes ground pins may be unlabelled but still need connection.
Type · GroundVoltage · 0V ground return.
INPUT connector
HUB75-style input ribbon connector; Adafruit distinguishes INPUT from OUTPUT and explains labels/arrows/notch orientation can identify the input connector.
Type · Unknown
OUTPUT connector
HUB75-style chained output ribbon connector; Adafruit notes panels support chaining, though Arduino-class use is impractical and their Arduino library does not support chaining.
