About the ADC ECU Board

ADC ECU Board is an open source STM32 PCB design by UC-Aerospace, published on GitHub. It is a 4-layer board measuring 100 × 50 mm, with 136 components from 59 distinct parts.

Its main chip is the STM32G0B1RCT6, from the STM32 family. Other key parts include the TCAN1046AVDYYRQ1, AZ1117CH-3.3TRG1, AZ1117CH-5.0TRG1 and ADS124S08IRHBR. By type, the board carries 58 resistors, 42 capacitors, 18 connectors, 7 diodes, 5 ICs and 2 fuses.

From the project

This repo contains the hardware and firmware for the 2025 Hybrid Rocket Engine FYP test stand electronics.

This repo contains the hardware and firmware for the 2025 Hybrid Rocket Engine FYP test stand electronics.

The hardware consists of three seperate modules, the central ECU alongside a servo and ADC peripheral. Central to peripheral communication uses CAN-FD and is designed to be modular, while communications to a remote interface unit is done over RS422. For more information on the RIU it can be found here.

ADC ECU Board: common questions

What microcontroller does the ADC ECU Board use?

The ADC ECU Board is built around the STM32G0B1RCT6, from the STM32 family.

How big is the ADC ECU Board?

The ADC ECU Board measures 100 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ADC ECU Board?

136 components, from 59 distinct parts. The full bill of materials is listed on this page.

Where can I download the ADC ECU Board design files?

From the UC-Aerospace/Hybrid25_ECU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ADC ECU Board design in my own project?

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

Can I test firmware for the ADC ECU 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.
