The V3 of the design was ready for production on 22 July. We’d like to produce 70 of those cards of this version, apart from the fact that a user at GSI just found a mechanical problem that could appear with a certain combination of SFP plugin and PC type. Being just in time to correct this by simply moving the SFP 2.5 mm further out on the PCB, we decided to make a V4 of the PCB.
Why a V4 while the V3 never was produced? As this will ease the tracibility as possibly copies of this Open Design design may already be around!
