-Open hardware for a hackable scintillation counter and multichannel analyzer (MCA) all-in-one device using a popular NaI(Tl) scintillation crystal and a silicon photomultiplier (SiPM). Extremely affordable design for a DIY gamma spectroscopy setup with a total parts cost of under around 200 USD.

-The detector uses a standard serial-over-USB connection so that it can be integrated into as many other projects as possible, for example data logging with a Raspberry Pi, weather stations, Arduino projects, etc.
+The detector uses a standard serial-over-USB and hardware UART connections so that it can be integrated into as many other projects as possible, for example data logging with a Raspberry Pi, weather stations, Arduino projects, etc. It includes both scintillation counter and multichannel analyzer (MCA) functions depending on how you want to use it.

-If you want a barebone version of the Open Gamma Detector to count pulses only or similar, you can have a look at the [Mini SiPM Driver](https://github.com/OpenGammaProject/Mini-SiD) board.
