No soldering required for easy setup. Switches allow on-the-fly voltage changes. Terminal block can be used to provide power to your robot, display, LEDs, etc. Green LED output indicates that the terminal block power is on - can be disabled if preferred. Stemma QT for I2C control plug-and-play with Qwiic/QT; USB Data lines available on solderable pads. The HUSB238 USB PD sink chip is neat in that you can either use switches (really, resistor selection) to set the desired PD voltage or use I2C for dynamic querying and setting. We already stock a simple USB Type C Power Delivery Dummy Breakout board around the HUSB238, but that one requires soldering closed jumpers to select the voltage. For folks who want a no-soldering-required board, this USB Type C Power Delivery Dummy - I2C or Switchable is ready for instant gratification.
