data output for RF Tx module.
NC
Input pin with Schmitt trigger. If this pin is logic low, the controller will keep in
reset condition
Ground
Left button input pin (internal pull-high resistor)
Right button input pin (internal pull-high resistor)
Middle button input pin (internal pull-high resistor)
