1 Signal GND shield over IC and input-side pads.

of 2 u.fl connectors added instead of 2.54mm pin headers.

3 pin diode array with Pb aperture. Signal GND inside is left disconnected from the sensor head chassis GND and only connected on the DDC118 board.

4 An incomplete iteration - the LDO is still on Rev.1E. Attempts were made :)Should I have a need to build another board, it'll probably look very different today.
