Of course I stand to be corrected by my mentor:apologetic: but I have a similar bob (but not the same) and that has to be connected to enable the bob. ..CliveQuote:
The VDD Clive mentions is if you use 10V I think and you have to change a jumper on the board if using 10V.
Edit: looking at the schematic and the picture of the bob they are both different in that the schematic shows : 5V gnd gnd 10V but the pictures shows 5V gnd gnd 5V
