I think I damaged my board?

I have had my board connected to the Visual Sequencer a few times, and it was working fine as per the manual.

SC-32, 12 HS-5645 servos, 7.4v to VS1 powering everything.

With the power turned on the servos make full sweeps, jitter, everything but remain still as they did previously. Trying to connect to the board with Visual Sequencer is now fruitless as well.

Thanks.

If your servos are jittery, it is likely that the logic voltage is too low. Please make sure you are using a proper power supply at the logic.
