Background
Owner of the LED mats has about 40m2 in total, has multiple power supplies but no "control box". The power supplies contain a Receiver Card, the missing component is the Sender Card.
The owner would like to hang some mats on the side of his van when parked at events, so he can display text (dynamically). Since he only needs a small amount of the mats, the unused mats need the same.
