It belongs with the sensors and science & space designs in this gallery.
From the project
Upadted clean sheet design
In plain English: High-energy particles called muons constantly rain down from space. Muon3 builds small, portable detectors ("muon telescopes") that use special plastic panels. When a muon passes through, the plastic gives off a tiny flash of light that is captured by sensitive sensors and fast electronics.
The project aims to network many of these affordable detectors (using cellular links for remote control and data). This lets researchers study cosmic ray air showers, monitor space weather, and do basic directional measurements with muons. It supports both scientific research and…

Muon3-board: common questions
What microcontroller does the Muon3-board use?
The Muon3-board is built around the RP2040, from the RP2040/RP2350 family.
How big is the Muon3-board?
The Muon3-board measures 160 × 120 mm, has 4 copper layers and is 1.6 mm thick.
