User Manual

A 32x16 panel uses this pin arrangement. The labels

might be slightly different, or the pins might not be

labeled at all…but in either case, use this image for

reference.

Notice there are four ground connections. To ensure

reliable performance,

all four

should be connected to

GND on the Arduino! A solderless breadboard is handy

for making this split.

Here’s the layout for 32x32 and 64x32 panels. We’ll call

this “Variant A.” Some panels use different labels, but

the functions are identical.

The layout is very similar to the 32x16 panel, with pin

“D” replacing one ground connection.

This is the layout we’ll be referencing most often.

If you have a 32x32 panel with

no pin labels at all,

then

use this layout.
