This is my spectrometer board. The C12880MA module sits in the middle, no front optics yet. I also used couple of transistors for simple 3.3V -> 5.0V level shifting and couple of by-pass caps to keep +5V source noise low. The actual schema will follow later...

I decided to make my own controller board. It has a PIC 24FJ64GB002 microcontroller running with 26MHz oscillator. It also uses a FTDI USB module and is powered via USB connection.

********************************** The Spectrometer Project short description rev. 26.11.2018 ********************************** The heart of this instrument I'm building is Hamamatsu minispectrometer module, part number C12880MA. It is a module including grating + sensor + interface electronics, all hermetically packed inside a metal can with footprint only slighly larger than a regular 14-pin dil component. Light enters through… Continue reading My Plan for a Miniature Spectrometer
