The LDO at U2 is the wrong footprint

Problem environment

The low dropout voltage regulator for USB bus power according to the bill of materials must fit the layout footprint.

Steps to reproduce

  1. Reference the parts list and layout
  2. Examine the LDO with designator U2
  3. Compare the size and footprint

Expected result

The size and footprint of the part specified by the bill of materials is consistent with the layout design.

Actual result

The layout design indicates a different footprint than the bill of materials specifies.

Workaround

A nasty hand soldered fine pitch effort is possible if a high quality microscope and solder station is used. Solder the terminals of the LDO by hand.

Severity level

This is low priority because project requirements imply no support for serial interfaces, except for UART/RS232 needed for host communication.
