README
README.mdRocketFlightController
I decided to design a custom flight controller because i wanted to learn more about custom PCBs and overall sensors and microcontrollers workflow, while trying to master soldering along the way :p
Components
- ESP32-WROOM-32E - i used this module in Kicad, it is a great microcontroller which can be accessed remotely because of its wifi/bluetooth modules.
- BMP280 - pressure sensor which can be used to approximate height which is crucial for drones, rockets and etc.
- MPU-6050 - simple accelerometer which also has a gyroscope used to determine tilt/angle I also decided to make spaces or pins for 4 servos, as i planned to allocate 2 of them for TVC(thrust vector control), and other 2 for an active recovery system.
And there is a bunch of capacitors, resistors, some buttons which are all used on a single custom PCB, all parts of which i will list in BOM list in the end.
The entire board can be powered from a standard 5 V battery pack or USB power bank. I did not include it in the BOM because it is a common off-the-shelf item that users can easily purchase separately.

Questions
How big is the RocketFlightController PCB?
It measures 63 × 62 mm and has 2 copper layers, 1 mm thick.
What parts does the RocketFlightController use?
25 parts, built around the ESP32-WROOM-32E, BMP280, AMS1117-3.3 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 RocketFlightController KiCad files?
From the Tiladura/RocketFlightController repository on GitHub, at the commit this page was made from: the board is Kicad files/kicad.kicad_pcb and its schematic Kicad files/kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RocketFlightController design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tiladura before reusing the design.
