Hello, Kniggles.

I have changed the subject of your post to be more appropriate.

We have not yet released any firmware upgrades for any of the Mini Maestro servo controllers. You probably used the firmware file for the Micro Maestro. Your Maestro has invalid firmware now but the bootloader should still be there so we can use it to put the correct firmware back on the controller. Please email us directly so I can send you instructions on how to do that.
