2.2.3 Power

The EVM is designed to operate off of a 5V VBUS from a USB-C host connected via the USB Type-C plug connector. Apply no external power via J5, unless standalone operation is desired.

Care must be taken that the Type-C VBUS is negotiated at 5V only. If a VBUS greater than 5V is anticipated, then the EVM must be powered via an external 3.3V source. Take the following steps to make sure the EVM is not damaged in this case:

  • Remove the 5V → 3.3V LDO (U2) from the EVM
  • Remove resistor R40
  • Remove any SHUNT on J4 and J6
  • Apply 3.3V to the left header of J4 and the right header of J6
