Notes and Changes:
The datasheet for the photodiode used in this design (C30642) can be accessed at: https://www.pacer.co.uk/Assets/User/1645-Large_Area_InGaAs_PIN.pdf

Version 8 - Had to order more boards. Brought PCB up to revision 8 and incorporated single supply protection features listed in version 7. Went through entire bill of materials and created variants for Squeezer CLF and OPO detectors
