MY V5 also arrived within the last week and I went to check the pinout first thing this morning and saw the V6. I was dismayed at first, until I realised the V5 with the USB B interface and standard 0.1inch pitch actually suits me better than the V6.

I have tons of USB B cables around, and I can build 0.1inch pitch connectors over and over, without worrying about having a V6 that gives you 1 chance to damage the wiring.
