Follow the circuit diagram below and reference the connections for wiring the circuit. Lay out the parts and circuits as shown and then measure each wire with enough slack to solder each component. Lable each set of wires to keep track which wire goes where.
Remove the driver from the display to make soldering easy.
Use a panavise to hold the board in place while soldering.

Solder Video - (3rd pin) to the 2nd pin on the FPV receiver.
Connect the 1st pin on the display to the 5v on the powerboost.
The 2nd pin on the driver connects to the G pin on the powerboost.
The order of the pins for the Brightness button don't matter.
The 1st pin on the FPV connects to + on the powerboost.
The 2nd pin on the FPV connects to the - on the powerboost.
The order of the pin for the Band and Channel button don't matter.
