This is third edition of Arduino Compatible DIY Geiger Kit developed by RH Electronics. The kit is simple radiation detector board that provides visual and audio signalization of each Geiger event. The PCB allows installation of SBM-20 or LND-712 tubes. Many others GM tubes models can be connected with wires to the board.

Geiger Tube is not included!

400V or 500V tube voltage range is selected with jumper. In addition, the board has wide compatibility with different microcontrollers and Apple devices. The kit is very easy to solder, you need to solder only through-hole DIP components, when all SMD parts already installed on the PCB. If you are software developers, you can integrate the board to your environment with your favorite micro-controller added.

Benefits of original third edition:

Kit consumes less than 0.06mA at background, usually 0.035mA
Improved HV stability up to 1000uSv/h radiation load
More supported tubes, 400V and 500V range select
Tube over voltage protection, limiting HV spikes
Wide compatibility with different MCU for software developers
TRRS socket for direct connection to Apple devices for “Geiger Bot” or for Android
Only DIP components to solder, SMD already installed
Simple assembling, no need to read electrical circuit
