Ordered most of the parts by now, and sent the Power Supply and Digital boards for production. Will wait until the ICs I ordered arrive because I am not sure which of the SMD IC footprints I should use; Kicad has updated the libraries from version 4 to 5 and now I am not sure which is the footprint that better fits the actual component.

Changing the footprint will require some rework on the traces that run under the ICs because the new footprint is narrower, leaving less room for the traces. The plan is to print both layouts on paper soon as I receive the ICs and then place the actual component over the printout to verify which is the best for hand soldering.
As the Digital Board uses only thru-hole components, I decided to send this board to production first. Will place pictures soon as I receive them!
