Hi, I want to use a 128X64 matrix board, where should I plug line E?

Pin 10 on the Pi

As shown here here

Connections per chain

Then for each first panel of a chain there is a set of (R1, G1, B1, R2, G2, B2) that you have to connect to the corresponding pins. They are marked [1], [2] and [3] for chain 1, 2, and 3 below.

If you only connect one panel or have one chain, connect it to [1] (:smile:); if you use parallel chains, add the other [2] and [3].

To make things quicker to navigate visually, each chain is marked with a separate icon:

[1]=:smile:, [2]=:boom: and [3]=:droplet: ; signals that go to all chains have all icons.
