Servo and Calibration Issues

Probably took out the shield, the arduino is probably fine. Looks like Maker Made and East Bay are out of stock.

Edit: I would contact whoever sold you the kit, vendors are pretty good at supporting customers.

Looks like Metal Maslow sells an assembly, make sure this is what you need:

Sometimes people make these and have them for sale, check the swap meet part of the forum:

Various versions of the shield board are listed in the community garden.

There have been a few diy shield boards using parts from overseas.
