Power Prep
The MatrixPortal supplies power to the matrix display panel via two standoffs. These come with protective tape applied (part of our manufacturing process) which MUST BE REMOVED!
Use some tweezers or a fingernail to remove the two amber circles.
Power Terminals
Next, screw in the spade connectors to the corresponding standoff.
- red wire goes to +5V
- black wire goes to GND
Panel Power
Plug either one of the four-conductor power plugs into the power connector pins on the panel. The plug can only go in one way, and that way is marked on the board's silkscreen.
Dual Matrix Setup
If you're planning to use a 64x64 matrix, follow these instructions on soldering the Address E Line jumper.
Board Connection
Now, plug the board into the left side shrouded 8x2 connector as shown. The orientation matters, so take a moment to confirm that the white indicator arrow on the matrix panel is oriented pointing up and right as seen here and the MatrixPortal overhangs the edge of the panel when connected. This allows you to use the edge buttons from the front side.
Check nothing is impeding the board from plugging in firmly. If there's a plastic nub on the matrix that's keeping the Portal from sitting flat, cut it off with diagonal cutters
