WIRING DIAGRAMS
While this board supports only TTL +5VDC signals, different kind of sensors, switches
using different voltages can be connected using the diagrams that follow:
Note.
This board has two possible inputs banks, (bidirectional pins: 2-9) and (dedicated inputs: pins 10, 11,
12, 13 and 15), and all the inputs of the same bank have the same configuration. The below wiring diagrams
are an example, any input can be used for the connections.
Note.
The wiring bellow requires setting the input to be used in pull-up mode.
