# PrincipIoT Flight Controllers

##

Welcome to the official documentation hub for the PrincipIoT family of flight controllers.\
We design high-performance, reliable hardware for FPV drones, UAV research, and autonomous flight applications — built to make advanced capabilities more accessible.

Here you’ll find quick start guides, specifications, pinouts, firmware instructions, and troubleshooting for:

* **Coming Soon -** [**H7 Pi**](/principiot-docs/h7-pi/overview-and-specifications.md) – STM32H7 + Raspberry Pi for advanced onboard computing
* [**F7 Pi**](/principiot-docs/f7-pi/overview-and-specifications.md) – STM32F7 + Raspberry Pi for cost-effective autonomy
* [**F7**](/principiot-docs/f7/overview.md) – Pure STM32F7 performance in a compact form

Whether you’re a hobbyist, researcher, or developer, our boards are made to integrate seamlessly into your build and grow with your needs.
