About the Horizon PCB

Horizon is an open source STM32 PCB design by ChladpavPy, published on GitHub. It is a 4-layer board measuring 38.4 × 82.8 mm, with 92 components from 40 distinct parts.

Its main chip is the STM32F405RGTX, from the STM32 family. Other key parts include the BMP580, E22-900M22S, MS561101BA03-50, W25Q128JVSIQTR and ICM-42688-P. By type, the board carries 36 capacitors, 26 resistors, 8 ICs, 8 diodes, 6 connectors and 3 transistors.

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

From the project

Custom Rocket Flight Controller

So first I want to explain, why I started this project. I have always wanted to build my own rocket, but for a long time it was just impossible and senseless. It is generally prohibited to fly with your own custom rockets, there was nowhere to safely test them, and it could be very dangerous. But then I noticed the ČVUT rocketry challenge, where it is actually possible to do it safely and legally.

Horizon: common questions

What microcontroller does the Horizon use?

The Horizon is built around the STM32F405RGTX, from the STM32 family.

How big is the Horizon PCB?

The Horizon measures 38.4 × 82.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Horizon?

92 components, from 40 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 Horizon design files?

From the ChladpavPy/Horizon 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 Horizon design in my own project?

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

Can I test firmware for the Horizon 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.
