Read More…The PrincipIoT Node is an ESP32 coprocessor designed for use on FPV drones. Easily add wireless connectivity, or extend the functionality of your flight controller through custom programs without needing to modify the flight controller. It's the same footprint as a standard 30x30mm flight controller for easy integration.
It features onboard Wifi, Bluetooth, and Bluetooth LE and can easily be programmed through the Arduino IDE or using the Espressif ESP-IDF. An onboard I2C bus is also exposed for easy interfacing with sensors or actuators, compatible with the Sparkfun QWIIC and Adafruit Stemma standards. Don't worry about combing through schematics to find what pins are connected where, everything is marked in silkscreen on the back side of the board for easy referencing.
There's several ways to use this on a drone...
Using the onboard web server, fly a drone using only your phone. Simply upload the RC Control program (Github link here) and connect the UART to a UART port on any MSP enabled flight controller. Now you can fly using joysticks in your browser.
This can form a UART to TCP/UDP bridge, enabling wireless configuration of your drone with ESP-Serial-Bridge (https://github.com/yuri-rage/ESP-Serial-Bridge). Once uploaded, use TCP port 8881 or UDP port 14551 to communicate with an attached flight controller.
Easily add your own custom application by writing software in Arduino or ESP-IDF. Try out any of the QWIIC (https://www.sparkfun.com/qwiic) or Stemma (https://www.adafruit.com/category/1005) compatible sensors just by plugging them in, no extra wiring needed.
