Betaflight Settings: 
Locate UART TX/RX pad resource ID you are using.  We wired to RX4 in this demo. RX4 is A01  Note the name of resource and ID. 
Next we will clear that pad from its assigned resource.
Next we will set the Custom Mode Switches. We will set up 1 switch Copy and past these Commands into CLI:
set pinio_box = 40
aux 2 40 2 1600 2100 0
Next we need to assign the Resource ID to the Custom Mode switch. Using the Resource ID from above. "A01"
resource PINIO 1 A01
If you wish to set up more pads for additional RealPits. replace the area in brackets with your resource IDs: Copy these extra lines to add more modes as well.:
set pinio_box = 40,41,42,43
aux 3 41 3 1600 2100 0
aux 4 42 4 1600 2100 0
aux 5 43 5 1600 2100 0
resource PINIO 2 [resource=I.E=A04]resource PINIO 3 [resource=I.E=A05]resource PINIO 4 [resource=I.E=A06]
Type  SAVE  in CLI and then press enter. Your FC will reboot after applying changes. 
Now go to Modes and Assign an AUX channel to the USER1  mode. Just like an arm or turtle mode switch. Click SAVE. 
Now flip the switch and test. A RED LED will be lit on RealPit if your are providing power.
