OpenGammaKit is an open-source gamma spectrometer hardware platform, inspired by the excellent Open-Gamma-Detector. It takes the original schematic and redesigns the PCB using KiCad (originally designed in EasyEDA), making the project more accessible and modifiable for open hardware enthusiasts.

OpenGammaKit is designed to be affordable, reliable, and easy to integrate with embedded systems, mobile devices, or PCs—ideal for DIY nuclear instrumentation, educational labs, or citizen science.

🔧 Features

✅ Based on the Open-Gamma-Detector schematic

✅ Complete redesign in KiCad with improved layout and routing

✅ USB serial communication (compatible with Android 7.0+ and PCs)

✅ Compatible with OGK Inspector Android app and OGK Firmware

✅ Real-time gamma spectrum output and spectrometer integration

✅ Works with scintillation detectors (e.g., CsI(Tl), NaI(Tl), etc.)

✅ Open and editable source files for schematics and PCB
