Navio / Edge Getting started

good evening, thank you for your great work, I have a question about the pinouts on the Navio2 and Rasberry pi 4B board, which pins can we use other than the Gpio26, Gpio17 and Gpio18 pins?

Hi @Jack1383,

You can check the pinout scheme in the following guide. The GP26 (pin 37) on Raspberry Pi is free as well as the IO17 and IO18 pins on UART. The rest of them are occupied.
