From the project
All-in-one FPV drone PCB with integrated flight controller, PDB, and ESCs built around STM32F411.
A comprehensive, fully open-source FPV drone platform: a two-board avionics stack (flight computer + power/ESC) complete with their codebase and a lightweight, robust airframe. All KiCad 9.0 design files, firmware, and CAD are included. Media of all PCBs, schematics and airframe are attached within this repository.
This project develops an FPV drone around two custom 5×5 PCBs: a STM32F411 flight computer and a STM32F405 power distribution + ESC board. esigned for compatibility with Betaflight (FC) and AM32 (ESC). Both are built around the STM32 chipset and designed to be compatible with…

ESC Board: common questions
What microcontroller does the ESC Board use?
The ESC Board is built around the W25Q16JVSSIQ, from the STM32 family.
How big is the ESC Board?
The ESC Board measures 48.8 × 53.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ESC Board?
70 components, from 47 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 ESC Board design files?
From the FPV-Drone-STM32F411/DroneController 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 ESC Board design in my own project?
The repository has no license, so all rights stay with FPV-Drone-STM32F411. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESC Board 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.
