CH32X035 USB PD Tester

# USB PD Tester The USB PD Tester is a monitoring and triggering device designed for USB Power Delivery. It allows you to test a wide range of USB Type-C PD power supplies and their corresponding cables. This tool not only displays the capabilities of the power supply on an OLED but also enables you to select one of the available fixed or programmable voltages for output on the screw terminal. With this, it can also be used to power your projects with various selectable voltages and high currents, serving as a versatile variable power supply. The USB PD Tester is built around the inexpensive (30 cents at the time of writing) and user-friendly CH32X035 RISC-V microcontroller, which comes with integrated USB 2.0, USB PD 2.0/3.0, and USB Type-C hardware support. - Project video (Youtube): https://youtu.be/wqLiRnbcISo - Project files (Github): https://github.com/wagiminator/CH32X035-USB-PD-Tester    # Operating Instructions 1. Connect the USB PD Tester to a USB Type-C PD power supply using a USB-C cable. The available PDOs and their corresponding capabilities are displayed on the OLED. 2. Utilize the UP and DOWN buttons to choose the desired PDO. A left-angle bracket on the right side serves as the selection indicator. Programmable PDOs, indicated by numbers within square brackets, allow precise adjustments of the output voltage in 20mV steps within the specified range. 3. Press the SLCT button to activate the chosen PDO. An asterisk on the left side of the PDO confirms the activation. 4. The selected voltage is now accessible on the screw terminal for further use.    # License  This work is licensed under Creative Commons Attribution-ShareAlike 3.0 Unported License.
