New SiPM carrier boards

A project log for All-In-One Gamma-Ray Spectrometer

More sensitive to gamma radiation than a Geiger counter with the added bonus of telling exactly what's inside your samples!

Finally I came around to finish the carrier board for the new Broadcom AFBR-S4N66C013 SiPM!

You can find all the info - as usual - on GitHub. A Kitspace link will also be available very, very soon.

In addition to that, I also re-did the "old" MicroFC PCB. The generic bias filter is now optional (enable by soldering to VCC and GND and close the solder jumper JP1) and you can directly solder across the SiPM via the cathode C and anode A pads.

I also removed two caps as I don't think they were that useful after all and now the detector capacitance is lower too, yay!
