GPIO Setup

GPIO Layout

We are using the Jetson TX2 Orbitty Carrier for our plane, Toothless. A useful manuel for knowing the pin layout is found here on pages 11 and 12. When SSHing into the Jetson, each pin is identified as GPIO ###, for example our pin used for the LSB in our drop mechanism is identified as GPIO 298.

The pins that we can transmit signals and receive from are GPIO pins 7-10, which on the Jetson ssh are labeled as GPIO 388, 298, 480, and 486. Information on the pin designations can be found here. These are used to write a script on the Jetson to send the correct high or low signals for the arduino to interpret.
