This breakout is built around the HUSB238 USB PD sink chip, making it easy to negotiate power from a USB Type-C Power Delivery source without soldering tiny resistors. It plugs into a USB-C cable and uses the CC lines to request a suitable PD voltage.
You can configure it with solder jumpers for fixed output voltages including 5V, 9V, 12V, 15V, 18V or 20V. By default it is hard-wired for 5V 1A output, and you can also select desired current from 2A to 3A. No microcontroller or microcomputer is required for jumper-configured use.
For dynamic control, connect it over I2C to a separately powered microcontroller or microcomputer with suitable I2C pull-up resistors. Adafruit provides an Arduino library and example code to query a USB Type-C PD source for available voltages and currents, then select the desired voltage.
It comes with a small bit of header and a terminal block, so you can choose between breadboard-friendly use or free-wired installation in your project.
Specifications:
- Product Dimensions: 24.5mm x 20.2mm x 4.9mm / 1.0" x 0.8" x 0.2"
- Product Weight: 2.2g / 0.1oz
Useful for converting DC or battery-powered projects to USB-C power, or for projects needing more than the basic 5V available from a typical USB connection.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
- Type-C
- USB Type-C (USB-C) is a small, reversible USB connector used for charging, power, and data transfer on many modern devices. A Type-C port or plug indicates the cable and charger connection needed to power, charge, or communicate with a device.
- USB Type-C
- USB Type-C is a small, reversible USB connector used for power, data and sometimes video on many modern devices. The connector itself does not guarantee a particular speed or voltage, so check the supported USB version, data rate and whether it carries more than 5V via USB Power Delivery.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
