While putting the kit together I noticed there are 2 different types of ceramic capacitors. One's marked with 105 and the other 473. In the instruction book, it mentions the 105 capacitors but there's no mention of the 473 ones nor is there anywhere on the board for them to go. So, my questions are, where do they go and what's the difference between the two?
There's also some really small, black headed components that I have no idea what are. There's no place on the board for them and no mention in the instructions. What are they?

Hi James, The 473 capacitors (47nF) are for the current sensor. There should also be a 4.7nF in there for the current sensor. Instructions for these are in the 'connecting the eChook to the car' section of the documentation. The two other black components with three legs and square tops are the hall effect sensors for wheel and motor rpm. The two black components with round tops and two legs are the thermistors. I'll update the documentation to make this clearer  Thanks, Rowan. |

I have just got around to sorting this out after a long while away.
I have 2 473 capacitors so 47nf but I have a 472 capacitor and one with 05 on it . I assume that the 472 is the 4.7 capacitor .

I imagine the 05 capacitor is supposed to say 105 - the printing can be a bit dodgy. You should have three of these though... |

Greta , as I soldered it as such.
I managed to get a few extra parts so i guess it was a spare 105.
Next question,
Looking at the connecting the eChook to the car pages and specifically the connector/pin/signal use chart am I correct in thinking the order for the chart is random . In other words the screen prints on the eChook board is correct and not the order on the chart.So motor PWM is not in reality next to RPM as it is in the chart.

Where minimum order quantities have left us with extra components we've added a few spares to the kits, it is a little luck of the draw though.
You're right, the table isn't ordered. Go by the silk screen on the board to identify the connectors. I'm not sure why I did it in the order it's in, I'll reshuffle it into something more sensible!
