PCB Converter Adapter 3.5mm Audio to TRRS 4 pole ; Compatible with Geiger Bot

Description

Adapter PCB for Geiger Bot with adjustable voltage attenuation. The board helps to connect 3.5mm audio cable to 3.5mm TRRS Apple input. When TRRS cable is connected through this adapter then iPhone / iPad Geiger bot application will automatically switch into line input mode and will turn off microphone. The adapter is useful for different Geiger Counters or Gamma Spectrometers with audio interface to connect with Geiger Bot.
Take note, the input jack of the PCB is not DC decoupled, so for some third side devices you need to add bypass capacitor.
Important note:
Originally this adapter was designed for our Gamma-Viewer Portable Spectrometer to help easy switch between PC computer line in signal level to Apple microphone input level. I cannot guarantee electrical compatibility with all third side devices. You are responsible for any possible damage caused by the adapter. Please check pinout diagram in product photos!
