Script UART communication

This example uses Script node for UART communication. Note that OAK cameras don't have UART pins easily disposed, and we soldered wires on OAK-FFC-4P to expose UART pins.

Demo

Setup

Please run the install script to download all required dependencies. Please note that this script must be ran from git context, so you have to download the depthai-python repository first and then run the script
Command Line
1git clone https://github.com/luxonis/depthai-python.git
2cd depthai-python/examples
3python3 install_requirements.py
For additional information, please follow the installation guide.

3NOTE: This should only be run on OAK-FFC-4P, as other OAK cameras might have different GPIO configuration!
