SDCM3

Readout electronics

The SDCM3 electronics is a versatile low cost, one-board solution for certain linear sensors and Hamamatsu micro spectrometers. It can be extended to a complete portable Bluetooth-device, using its Piggy-back board.

Supported sensors

  • S11639, S13496x, S8378 (CMOS)
  • G11620 (InGaAs)
  • C12880MA (Hamamatsu micro spectrometer)
