The standard offerings are 5V, 9V, 12V, 15V, 18V, and 20V. This HUSB238 breakout plugs into the USB C cable and negotiates the PD request and commands over the CC lines. For example, we can ask what voltages are available and pick the highest. Or if you need a specific voltage, it will select that one.\u003c\/p\u003e\n\u003cp\u003eThis 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! - and you could buck that down to get a ton of current at 5V or 12V if that's needed. Or use it to convert a DC or battery-powered device into a USB C powered one!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDIP switch-configured usage is simple\u003c\/strong\u003e: 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!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eI2C-configured usage\u003c\/strong\u003e is also available via a Stemma QT port.
