About the Flight controller PCB

Flight controller is an open source STM32 PCB design by epicgrowl, published on GitHub. It is a 4-layer board measuring 50 × 50 mm, with 59 components from 30 distinct parts.

Its main chip is the STM32F103CBTX, from the STM32 family. Other key parts include the MPU-6500, BMM150, KP464 and AMS1117-3.3. By type, the board carries 16 capacitors, 16 resistors, 13 connectors, 5 ICs, 4 switches and 3 diodes.

It belongs with the robotics & motion designs in this gallery.

From the project

Probably not a very good design, but fully functional and stable.

Flight controller: common questions

What microcontroller does the Flight controller use?

The Flight controller is built around the STM32F103CBTX, from the STM32 family.

How big is the Flight controller PCB?

The Flight controller measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Flight controller?

59 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Flight controller design files?

From the epicgrowl/flight-controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Flight controller design in my own project?

The repository has no license, so all rights stay with epicgrowl. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Flight controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
