About the Drone PCB FC v2

Drone PCB FC v2 is an open source STM32 PCB design by Ethansuttor, published on GitHub. It is a 4-layer board measuring 60 × 44 mm, with 61 components from 38 distinct parts.

Its main chip is the STM32F405RGT6, from the STM32 family. Other key parts include the AP2112K-3.3, USBLC6-2SC6, W25Q128JVSIQ, TPS5430DDAR and ICM-42605. By type, the board carries 24 capacitors, 15 resistors, 6 ICs, 6 diodes, 4 connectors and 2 switches.

It belongs with the robotics & motion, power & battery and sensors designs in this gallery, and the repository also holds 2 earlier revisions of it.

From the project

An 80×80 mm STM32F405 flight controller for a 4S freestyle quad, running Betaflight off a custom target I wrote. I built it to find out whether I could take an embedded system from a blank schematic all the way to something that actually flies.

Drone PCB FC v2: common questions

What microcontroller does the Drone PCB FC v2 use?

The Drone PCB FC v2 is built around the STM32F405RGT6, from the STM32 family.

How big is the Drone PCB FC v2?

The Drone PCB FC v2 measures 60 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Drone PCB FC v2?

61 components, from 38 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 Drone PCB FC v2 design files?

From the Ethansuttor/drone_PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Drone PCB FC v2 design in my own project?

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

Can I test firmware for the Drone PCB FC v2 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.
