Pomelo, a low-power, open-source gamma-ray spectrometer

A complete low power gamma ray spectrometer that can be used standalone or integrated into other projects

Overview

A complete gamma spectroscopy module that connects to a laptop or embedded system. Measuring less than 130mm x 40mm x 30mm It contains everything you need for gamma spectroscopy and nothing more. It features a detector assembly (Pomelo Physics) with scintillator and silicon photomultiplier, and supporting electronics (Pomelo Core) with bias supply, analog front end and digital electronics. Its USB and UART connections allow it to be connected to many things, such as a laptop, Arduino or Raspberry Pi. It has an integrated level shifter on the UART lines so it can communicate with both 3.3V and 5V systems.
