USB VBUS connection #28

Closed mwelling closed 4 years ago

mwelling commented 4 years ago

The R0 USB has connection issues.

This is due to the VBUS connection to the BMD-340.

The VBUS voltage going to the BMD-340 has a diode drop which causes issues. Instead we should connect J1 (USB connector) pin 1 directly to U3 (BMD-340) pin 66.
