About the CUBESAT PCB

CUBESAT is an open source STM32 PCB design by Lifearafter, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 90 mm, with 46 components from 26 distinct parts.

Its main chip is the STM32F446RET6, from the STM32 family. Other key parts include the ADXL345BCCZ, NEO-M8N-0, IAM-20380, MAGNETOMETER and LM75AIM_NOPB. By type, the board carries 20 capacitors, 12 resistors, 6 ICs, 3 connectors, 2 switches and 2 diodes.

It belongs with the science & space, rf & radio and sensors designs in this gallery.

From the project

A repository to store all the code from C.A.S.E

Welcome to the Compact Antenna Experimenter System Project repository! This project focuses on providing the necessary code and documentation to create a fully functional and electrically viable CubeSat. In this repository, you will find the software and firmware that drive the electrical components of a CubeSat, ensuring its proper functionality in space.

CUBESAT: common questions

What microcontroller does the CUBESAT use?

The CUBESAT is built around the STM32F446RET6, from the STM32 family.

How big is the CUBESAT PCB?

The CUBESAT measures 90 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CUBESAT?

46 components, from 26 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 CUBESAT design files?

From the Lifearafter/CASE 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 CUBESAT design in my own project?

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

Can I test firmware for the CUBESAT 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.
