From the project

Hybrid Rocket Engine Ignition System

This repository contains the design files for the valve controller used by CU Spaceflight to control our hybrid rocket engine. It is capable of actuating up to 10x 24W solenoid valves simultaneously and is controlled over RS422 or USB by a GUI.

Ignition: common questions

What microcontroller does the Ignition use?

The Ignition is built around the STM32F437VIT6, from the STM32 family.

How big is the Ignition PCB?

The Ignition measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ignition?

146 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 Ignition design files?

From the cuspaceflight/hybrid-ignition repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ignition design in my own project?

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

Can I test firmware for the Ignition 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.
