. . . with always wanting to tweak my board designs.
Anyways I made a few changes. I've went from 1206 to 0805 for all the surface mount passives. The on-board LED is now surface mount. Voltage and ground planes were added. Auto routed races were re-done with manually routed traces. It was a bit of a puzzle of tweaking the layout and trace placement to get good coverage of the voltage and ground planes. I've posted the updated KiCad and Gerber files.
