Communicate Jetson Nano 2GB with STM32

Hi, for my project I am required to send and receive signals to two different STM32 microcontrollers via GPIO pins. The first one is used to receive a start signal and data regarding our game configurations. The second one is used so the Jetson Nano can send a signal telling the STM32 to rotate the motors via L293D motor driver.

As I mentioned previously all of this is done by interfacing the two microcontrollers via the GPIO pins. I’ve tried to look online how to do this and I haven’t really found any resources of how to accomplish this. I’m also confused on which pins I can use on the Jetson Nano 2GB. If anyone has any advice, I would greatly appreciate it.

Edit: I forgot to mention I am programming this in Python. I now only need to send and receive a signal to/from one microcontroller. One of the signals is a 5V signal.

hello user24036,

you may refer to Serial Console Setup/Parameters for the setups,
please also check NVIDIA Jetson Nano J41 Header Pinout for the pinouts.
