About the STM32F7 FC PCB

STM32F7 FC is an open source STM32 PCB design by rishikesh2715, published on GitHub under the MIT license. It is a 8-layer board measuring 38.5 × 38.5 mm, with 127 components from 65 distinct parts.

Its main chip is the STM32F722RET6, from the STM32 family. Other key parts include the ICM-42688-P, AT7456E, BMP388, W25Q256JVEIQ and AZ1117-ADJ. By type, the board carries 47 capacitors, 29 resistors, 17 test points, 13 connectors, 8 ICs and 5 diodes.

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

From the project

STM32F722RET6 Based Flight Controller with ICM-42688-P IMU, BMP388 Barometer, and much more!

- Removing AT7456E based analog OSD and CVBS routing. - Targeting modern digital FPV systems. - Feel free to recommend any changes you wanna see. Just open an issue.

Hoping to have the new hardware done next month if life chills out.

STM32F7 FC: common questions

What microcontroller does the STM32F7 FC use?

The STM32F7 FC is built around the STM32F722RET6, from the STM32 family.

How big is the STM32F7 FC PCB?

The STM32F7 FC measures 38.5 × 38.5 mm, has 8 copper layers and is 1.70208 mm thick.

How many components are on the STM32F7 FC?

127 components, from 65 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 STM32F7 FC design files?

From the rishikesh2715/STM32F7_FC 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 STM32F7 FC design in my own project?

Yes, under the terms of its MIT license, which rishikesh2715 chose for the repository.

Can I test firmware for the STM32F7 FC 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.
