• Who

  • Daniel Puratich Architecture & Management

  • Kenny Na EE Designer

• What

  • A USB-C PD sink where we can select the output voltage with resistors

    • DNP and fitted resistors, should be foolproof 0805s

  • Intent for requesting 20V 65W when debugging https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2701197313/RPi+Interface+Rev+C?atl_f=content-tree setup without the full drone

    • should support 12V and 5V as well, for testing other boards

  • Use a USB-C PD chip and the associated required FETs that are required for negotiation

  • Ideally does not require a microcontroller, due to cost constraints

  • USB-C input connector / XT30 output connector

  • don't worry about board area too much but it can be tiny

  • no buck converter
