About the Open-Geiger-Mueller PCB

Open-Geiger-Mueller is an open source Raspberry Pi PCB design by schwallsunk, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 128.1 × 79.6 mm, with 27 components from 18 distinct parts.

Its main chip is the RaspberryPi_Pico_W, from the Raspberry Pi family. By type, the board carries 11 resistors, 4 switches, 2 transistors, 2 test points, 2 diodes and 2 capacitors.

It belongs with the science & space, iot & wireless and dev boards & breakouts designs in this gallery.

From the project

Open source Geiger Mueller counter

This repository should provide all the needed parts for the construction of low-cost entry-level Geiger Müller (GM) counter system. This counter was build by request from the students of 151-0163-00L Nuclear Energy Conversion at ETH Zürich. For a more complete description of the project please read the manual.

The repository itself is subdivided into two two main parts. The hardware parts contains all the relevant EDA files created in KiCAD v9. The software directory contains all the different code written and tested for and on the hardware.

Open-Geiger-Mueller: common questions

What microcontroller does the Open-Geiger-Mueller use?

The Open-Geiger-Mueller is built around the RaspberryPi_Pico_W, from the Raspberry Pi family.

How big is the Open-Geiger-Mueller PCB?

The Open-Geiger-Mueller measures 128.1 × 79.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Open-Geiger-Mueller?

27 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Open-Geiger-Mueller design files?

From the schwallsunk/Open-Geiger-Mueller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Open-Geiger-Mueller design in my own project?

Yes, under the terms of its GPL-3.0 license, which schwallsunk chose for the repository.

Can I test firmware for the Open-Geiger-Mueller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
