Note: The VIN pin is used to apply your own voltage to the I/O's of the module.
This voltage can be between 1.8V and 5V.
If the TTL levels are set to 3.3V or 5V via jumper assignment, the VIN pin serves
as the output.

: Until and including revision 1.2, these pins are inverted. In later revisions this
problem is solved.
