I thought you might want to see what it looks like while working (http://imgur.com/b8BJF). It works just as advertised and was very easy to assemble. Thanks!

Leaving the auto-reset cap N/C is useful for some soft flow control applications. Use the reset button and the bootloader will allow code to be uploaded within a short period of time.

The shield needs both the 5V for the digital circuitry and Vin for the motors. You can use the same Vin as in your arduino board (there is no Vin if you are sourcing the voltage from USB), so to use this shield, you need an external power supply. You can use a different Vin for the motors if you connect the male pin upwards and connect there a different source.

No LED means no power getting to the shield - pretty basic and easy to locate I would think. I have just started building mine, will post here if I have any problems.

I have added a little rubber bumper to prevent issues, but it seems way too close. Any other ideas?

The Freeduino board itself works just fine, it's only the motorshield that is not working. The power LED doesn't light up, whether the board is powered by USB or 12V dc, and the test program doesn't work with any of the motors I have tried. I was careful in assembling it to ensure that all components were oriented in the proper direction, and was careful with my soldering to establish secure joints, and there are no bridges or any sort of visible short. I would appreciate any advice you could give me, and I look forward to reading your response.
