1024-pixel RGB LED matrix panel, 32x32 at 6 mm pitch, with dual IDC connectors for chaining. Requires 13 digital pins (1:16 scan rate) and a 5V/4A supply per panel.

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.
Upper-half green channel data input on the matrix input connector; Adafruit notes label variants and colour-channel swaps on some panel batches.
Upper-half blue channel data input on the matrix input connector; Adafruit notes label variants and colour-channel swaps on some panel batches.
Lower-half red channel data input on the matrix input connector.
Lower-half green channel data input on the matrix input connector.
Lower-half blue channel data input on the matrix input connector.
Row address select input A for the RGB matrix panel.
Row address select input B for the RGB matrix panel.
Row address select input C for the RGB matrix panel.
Row address select input D for 32x32 and larger matrix panels where present.
Clock input; Adafruit states CLK is one of the signals that must be connected to the matrix input connector.
Latch/strobe input; Adafruit notes LAT may be labelled STB on some panel variants.
Output-enable input on the matrix input connector.
Panel power input; this 32x32 RGB LED matrix family is powered from 5V supply connections.
Ground return for signal reference and panel power; Adafruit notes ground pins may be unlabelled but still need connection.
HUB75-style input ribbon connector; Adafruit distinguishes INPUT from OUTPUT and explains labels/arrows/notch orientation can identify the input 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.
