About the Drone mark4 PCB

Drone mark4 is an open source STM32 PCB design by Keyrim, published on GitHub under the MIT license. It is a 4-layer board measuring 36 × 36 mm, with 66 components from 34 distinct parts.

Its main chip is the STM32F722RET6, from the STM32 family. Other key parts include the AP63205WU-7, TLV1117LV33DCYR, LSM6DSRTR, SPA06-003 and W25Q128JVSIQ. By type, the board carries 26 capacitors, 21 resistors, 8 ICs, 4 diodes, 3 connectors and 1 transistor.

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

From the project

A 5-inch racing drone is thrown by hand, motors off. The firmware detects the throw, predicts the apex of the parabola, spins the motors up ahead of time, recovers from an arbitrary attitude (the drone may tumble) and settles into a stable hover. Everything is rewritten from scratch - firmware, simulator, tooling - as a deliberate learning project. Behavioral reference: ArduPilot's "Throw Mode".

Drone mark4: common questions

What microcontroller does the Drone mark4 use?

The Drone mark4 is built around the STM32F722RET6, from the STM32 family.

How big is the Drone mark4 PCB?

The Drone mark4 measures 36 × 36 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Drone mark4?

66 components, from 34 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 mark4 design files?

From the Keyrim/drone-mark4 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 Drone mark4 design in my own project?

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

Can I test firmware for the Drone mark4 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.
