Adafruit USB Type C Power Delivery Dummy Breakout - I2C or Switchable

The HUSB238 USB PD sink chip is neat in that you can either use switches (really, resistor selection) to set the desired PD voltage or use I2C for dynamic querying and setting. This breakout will be handy for projects where you need a lot more than 5V @ 2A power: this adapter can give up to 20V at 5A - yes you can get 100W over USB C!

DIP switch-configured usage is simple: simply unplug the USB PD so you don't accidentally select too high a voltage for your device. Then switch ON the voltage you want: 5V, 9V, 12V, 15V, 18V, or 20V. You'll get that voltage and as much current as the adapter will provide. No microcontroller or microcomputer is required!.

I2C-configured usage is also available via a Stemma QT port. Use the Arduino library and example code to query the USB Type C PD source for available voltages and currents and select the desired voltage dynamically. When configuring over I2C, the jumper settings are used on startup until the I2C commands come over.

This HUSB238 breakout plugs into the USB C cable and then over the CC lines will negotiate the PD request and commands. For example we can ask what voltages are available (the standard offerings are 5V, 9V, 12V, 15V, 18V and 20V.) and then pick the highest one. Or if you need a specific voltage it will specifically select that one.

The new 27W USB-C Power Supply with Power Delivery (PD) will deliver a maximum of 5.1V, 5A enabling the Raspberry Pi 5 to power a wider range of peripherals. The total power drawn from the four USB ports on Raspberry Pi 5 is limited by default to a nominal 600mA; this limit is automatically increased to a nominal 1.6A when the USB-C PD Power Supply is detected.
