Product description: Power Delivery Dummy Breakout - power module with USB C connector - HUSB238 - Adafruit 5807
The Adafruit Power Delivery Dummy Breakout module with the HUSB238 chip allows you to dynamically select the voltage and current supplied by the USB C port, offering a wide range of output values: from 5 V to 20 V, with a maximum current of 5 A. This is as much as 100 W of power that you can use to power a variety of devices. The board allows both manual setting of parameters using jumpers , and more advanced users can use the I2C interface to dynamically set power parameters. The module can be used in projects that require more than the standard 5 V, as well as a power converter from USB C for DC-powered devices. Integrated USB PD (Power Delivery) negotiation functionality ensures automatic selection of the appropriate voltage and current from the power supply, making it an excellent tool for DIY projects, consumer electronics and professional applications.
The manufacturer has prepared a detailed user guide that makes it much easier to start working with the module. Check it out!
Power Delivery Dummy Breakout - power module with USB C connector - HUSB238 - Adafruit 5807.
The module allows you to obtain up to 100 W via USB C.
Main features of the module
- HUSB238 Chip : allows voltage and current configuration via jumpers or I2C.
- Voltage range : choose between 5V, 9V, 12V, 15V, 18V and 20V.
- Up to 100W power : maximum output of 20V at 5A, ideal for more demanding projects.
- Jumper configuration : settings without a microcontroller, voltage and current selection by changing jumpers.
- I2C configuration : dynamic voltage and current setting using I2C, with the possibility of integration with microprocessors.
- Universal use : can be used with various USB C power supplies, both for low-voltage devices and those requiring higher power.
Configuration using jumpers
By default, the board is set to output 5V/1A, which is what any USB C charger provides. To select a different voltage (e.g. 9V, 12V, 15V, 18V or 20V), just cut the 5V jumper and solder the appropriate jumper corresponding to the selected voltage. It is also possible to set the current from 2A to 3A, although in practice the device itself draws as much current as the power supply offers.
Configuration via I2C
Using the I2C configuration is a bit more involved. Since the output voltage (Vout) can be as high as 20V, the board does not have a built-in voltage regulator or pull-up resistors. To use this mode, you must connect the board to a microcontroller or minicomputer that has a separate power supply (or is able to regulate the voltage to 20V, if you intend to use such a high voltage) and add pull-up resistors for the I2C to the appropriate logical level. Then, using the Arduino library and sample code, you can dynamically read the available voltages and currents from the USB Type-C and select the desired parameters. The jumpers are used for initial configuration after power-up, but once commands are received via I2C, the parameters can be changed dynamically.
To select the voltage you can use the jumper or I2C configuration.
