  • LD1 should to be driven by transistor
  • consider connecting LDOs feedback to connector instead of one power pin.
  • change PCB name from "pcb"
  • add outjob file
  • add keep-out layer or adjust polygons to have separation from copper to edge
  • add pinout description to J15
  • 'Chassis ground' is not connected anywhere, not sure if that's fine
  • move IC1 and IC2 bodies from Mechanical1 to Mechanical13

I added it to avoid leaving the connector hanging loose.

Good point but I will leave it as it is. We didn't have any problems with the same circuit design and more complex ASIC (with higher current).

I also increased the distance between DSUB connectors - they were too close to each other.
