Adafruit USB Type C Power Delivery Dummy - I2C or Switchable
100 units available with a short lead time.
The Adafruit USB Type C Power Delivery Dummy (I2C or Switchable) lets you tap into USB-C Power Delivery to get 5V, 9V, 12V, 15V, 18V, or 20V from any compatible USB-C charger or wall adapter — no soldering required. Built around the HUSB238 PDL003A E-Marker variant, it can request up to 5A for a maximum of 100W over USB-C.
Select your desired voltage using the on-board DIP switches for instant, no-code operation, or use the STEMMA QT / Qwiic I2C port to dynamically query available voltages and switch between them programmatically. A screw terminal block provides easy power output to your project.
Key Features
- DIP Switch Voltage Selection – Choose 5V, 9V, 12V, 15V, 18V, or 20V with no microcontroller required
- I2C Control via STEMMA QT – Dynamically query and select PD voltages using I2C (DIP switch settings used at startup until I2C commands override)
- Up to 100W – Supports up to 20V at 5A with the E-Marker variant chip
- Screw Terminal Output – No-solder power connection to your project
- Power Good LED – Green LED indicates terminal block output is active (can be disabled)
- On/Off Switch Pads – Solder a switch between two pads to disconnect the internal pass FET
- USB Data Pads – D+/D- available on solderable pads for data applications
- No Soldering Required – DIP switches and terminal block for fully solderless setup
Ideal For
- Powering robots, LED strips, displays, and motors from USB-C chargers
- Converting battery or DC-powered devices to USB-C power
- Projects needing more than 5V @ 2A — get up to 20V @ 5A
- Dynamic voltage selection in I2C-controlled power systems
