I found the first version of Mini-MODBUS PCB a bit difficult to populate by hand (using a fine tip shouldn't be necessary). The component placement around the power supply was all but ugly, and pin description and other information were missing on the silkscreen.
The reworked design is a lot nicer (and also easier to assemble). Making better use of the limits of @oshpark design rules (vias, drill diameter, clearance and track witdh) was helpful. Schematics and size remained unchanged.
