This is just a basic box which features a XT60 plug, to connect batteries, a Power plug for the FPV (First Person View) Video goggles and an USB charger with an on/off switch.
What you need to build this is:
XT60 female plug
3 pin 5V female plug (the same as Arduino uses for 5V in.
USB plug (Female)
and a switch rated above 2A. The switch measures 13x19,8mm and is called a vippekontakt.
