The board was sent off for manufacture at OSHPark using their 4 layer service which was very cheap due to the very small dimensions (1.5x1.5cm).

Once received the board was populated using stencils from OSHStencils and a hot air gun. Software development then began to be able to control the motors over Bluetooth.

A close up photo of the assembled board can be found in the project gallery, but here's the board in an actual antweight robot:

This robot was controlled from a HobbyKing RC controller attached to another nanoARC (acting as a transmitter) via PPM from the controller. Here is a video of the board working to control the robot at a recent robot wars event:
