18-channel board but only 12 channels?


I just took delivery of a 18-channel board but it only shows 12 channels on the controller?
I tried flashing the firmware, but it will only take usc03a_v1.02.pgm for the 12-channel version but refuse to work when i flash the 18-channel version which is usc03b_v1.02.pgm


It looks like your Maestro was one of a few that were loaded with the wrong bootloader back near the end of 2014. I am sorry for any inconvenience this might have caused. If you email us at support@pololu.com, we would be glad to help resolve the problem.
