Most of the schematic is done. I do not foresee more than a few changes that might arise from the work on the PCB. The circuit turned out to be simpler than I expected, most of the issues were related to figuring out the power and routing between the driver and the ESD protection.

The PCB work in ongoing and so far the most challenging issue was the laying the power planes in the inner layer in a way that was simple but efficient.  Signals routing was pretty straight forward except for a few that needed to be routed through different layers.

Soon the first pass of the PCB routing will be done. The majority of is is done. There are several cosmetic issues that are still being worked on.

More posts coming soon.
