AAEON PICO-PTH4: Pico-ITX Board with Intel Panther Lake SoC · File : gpio-led-blink-python.py · Language : Python · Use case : Allumer et éteindre une LED via les broches GPIO de la carte.

Python script using libgpiod to control an LED connected to the internal GPIO pins of the PICO-PTH4.

The board features internal GPIO connectors accessible via Linux. Install libgpiod-python. Check the exact pin number in the AAEON technical documentation. Run with 'sudo python3 script.py' for hardware access permissions.
