• USB power input
  • USB host VBUS
  • VBUS (J4-1)
• USB return
  • USB host ground
  • GND (J4-5)
• Board logic rail
  • VCC (P1-1)
  • 3.3 V measurement point

Bench checks

• Identify the USB power input and ground in the board schematic.
• Measure roughly 3.3 V between the board logic rail and ground. Check for a short or wrong connector if the rail is low.
