The D1 board on the Zombieverter is just a piggyback board to allow web interface access to the VCU. Once you've set everything up, you can remove the board. It makes configuring the Zombieverter significantly easier since you don't have to mess around with serial cables.
If you like, you can leave it on and monitor your EV data via the web interface. But if the D1 flakes out the VCU will be unaffected.
Ah, that makes more sense then, good idea! I have personally blown up a laptop by having the USB section of a board it was plugged into hang around too close to an exposed 24V supply.
