README

This repo contains KiCad files for an open source flight computer PCB.
This 4-layer PCB is centered around an STM32F405RGT6 microcontroller.
It features:
MPU-6050accelerometer/gyroscope andNRF24l01radio module- one
UARTport - two
I2Cports - 4
PWMports to control the ESCs - USB 2.0
It is a pretty modest design, but it gets the job done.
I also designed a open source quadcopter frame that this board mounts on it. Check it out in here: https://github.com/aminjahanpour/quadcopter_frame
This project is free to use and modify by the public. Technically, you can do whatever you want with it :)

Questions
How big is the Flight computer pcb PCB?
It measures 51 × 60.1 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Flight computer pcb use?
87 parts, built around the STM32F405RGT6, NRF24L01P-R, SY8105ADC and MPU-6050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Flight computer pcb KiCad files?
From the aminjahanpour/flight_computer_pcb repository on GitHub, at the commit this page was made from: the board is F4.kicad_pcb and its schematic F4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight computer pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask aminjahanpour before reusing the design.
