Connectors

We debated whether or not to attach or specify power or motor connectors for the board. The pragmatic solution we chose was to just have connector holes drilled in the phase pads. The best solution both electrically and mechanically is to solder the wires to the board.

However if you want to attach connectors you should know the soldering pads on the board are for a 2mm pitch connector.

You could use a 2-row connector by soldering one row of the pin header to the board and manually wiring the 2nd row to it, to get 4-ways for each phase. See these connectors (links to Farnell in the UK) to get a better idea:
