I recently purchased the Output Plug.
http://news.jeelabs.org/docs/op1.html
It combines the MCP23008 8-bit port expander with a ULN2803 Darlington array which can drive up to 500 mA @ 50V.
I was hoping it could be used as a motor driver!! However I cant seem to get it working.
I'm not sure how to wire it up!!
EDIT:-
Arduino to Jeeplug Pin-Outs:
- DIO = SDA
- AIO = SCL
- +3V = 5V (this plug can be used at 5V - not all Jeeplugs can!)
- GND = GND
- Don't connect the outermost 2 pins of the plug.*
EDIT-:
I have tried asking the manufacturer but he seems quite busy sorting out the WIKI and Forum.

Does anyone here have any idea what the correct way of wiring the "VIN" and outputs to the plug?
Thanks in Advance
