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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- 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 chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
- USB Type-C
- A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
