Make sure that you have both of the new necessary parts, and that they're both undamaged.

The first part is the jumper board spacer which is made of solid white plastic.

The second part is the assembled jumper board, which should be marked with part number TD-TDMY-A and have 3 sets of 1x3 pin headers installed on it.

Check to make sure that none of the pins on the jumper board are bent. If any of them are slightly bent, you can attempt to bend them back into position with a pair of small pliers. If any of them are damaged, please contact us for a replacement.
