This is the control board that came with it....

The layout is

Left stick: L-R is A0, U-D is A1, Centre push is D2
Right stick L-R is A4, U-D is A3, Centre push is D4
LED is pin D3 but appears to be on a pull down circuit :o

There appears to be an issue with the board, it works when you connect only the pins in use to the board via jumper pins, if you push onto the board the arm goes crazy, I'd say there is a short in the PCB somewhere

Not the easiest build in the world, the frame is acrylic and brittle as anything. :o

Now to get the bloody thing programmed...... 8)
