Second Beta Build at fab.

I sent the files for the second beta version to the fab. I found and fixed 8 issues with beta 1. I also squished all the parts as close together as possible, It looks like this design could fit on a 4 layer 20x20mm board in the future. This one should be very close to a release candidate. ETA is March 28, a delay was added due to covid-19 virus. I am considering making a prototype test jig for this revision in the meantime. I need an easy way program and test boards before they are shipped to provide some QC. A second PCB with spring loaded pogo pins in a 3-D printed jig is what I have in mind. Since my 3-D printer has a resolution of .2mm I had to make sure my pads on the PCB are also centered at .2mm.
