Description

The expansion board connects to the central unit with the supplied cable.

The expansion board can accommodate up to 4 cards, each with a specific function and can be controlled by the central unit.

It is powered directly by the central unit, and it is possible to select either the Arduino or the direct power supply as a source via a simple Jumper (recommended solution when you need to power multiple cards or cards that require more current than the Arduino can supply).
