# Power supply The RDDRONE-T1ADAPT board needs an external 5 V supply. The 5 V supply can be provided by a PC or laptop via the USB connector on the bottom of the board, or via a 3-pin JST-GH power cord. ![](/files/-MaZJVVNkgZHrrvIRC3B) Note that the USB connector is only used to provide the 5 V supply; there is no actual USB data communication. The 3-pin JST-GH connecter is typically used with a single-board computer or device such as the NXP NavQ companion computer, or another DroneCode/PX4 device (pin 1 = 5 V; pin 3 = GND). Additionally there are two through holes on the board that can also be used to solder in wires or a custom connector of your choosing. ![](/files/-MaZJ_XyxXTnCcy9dzYL) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
