GPIO Control

Unlike the original PAB Carrier and Just a Jetson, the V3 does not route the Jetson's I2S0 pins to a dedicated GPIO connector. Jetson GPIO on the V3 is available on the Pixhawk Payload Bus and avionics connectors — see the Pinout for which pins carry GPIO-capable signals.

Additional PWM/GPIO capable outputs are provided by the flight controller side of the board: 16 PWM outputs (8 FMU + 8 IO) on the avionics connectors.

For how Jetson GPIO behaves on ARK carriers — idle states, libgpiod/Jetson.GPIO usage, and safe-state patterns for actuators — see the ARK Jetson Kernel GPIO docs.
