Rev0.5 If everything works, this is going to be rev 1.0

1. Use a better 1205 LED (much cheaper LCSC)
2. Fix the crystal CL, Rext
3. did a better job on wiring (but might come with power issues?)
4. fix the key position (0.01mm shifted so its a big fix)
5. generate better BOM file
6. add in LCSC and part number so easier to source
   Rev 0.4 is gone, I don't know where it went....
