DWEII USB-C PD Trigger Board Module Instruction Manual

Introduction

The DWEII USB-C PD Trigger Board Module is designed to convert USB-C Power Delivery (PD) and Quick Charge (QC) power sources into fixed DC voltage outputs. This module allows users to "trick" a fast-charging power bank or charger into outputting specific voltages (9V, 12V, 15V, 20V) to power various DC-powered devices. It supports multiple fast charging protocols, including PD3.0/2.0, PPS/QC4+, QC3.0/2.0, FCP, and AFC.

This manual provides essential information for the safe and effective use of your DWEII USB-C PD Trigger Board Module.

Setup and Voltage Configuration

The module comes pre-configured for a 12V output. To change the output voltage, follow these steps carefully. This process requires basic soldering skills.

1. Identify Voltage Pads: Locate the voltage selection pads on the module, labeled 9V, 12V, 15V, and 20V. These pads are typically arranged in a row with corresponding resistors.
2. Remove Default 12V Bridge: The module is factory-set to 12V. This is achieved by a very small, often hard-to-spot, zero-ohm resistor or solder bridge connecting the 12V pad. It is crucial to remove this existing bridge before attempting to set a new voltage. Failure to do so may result in incorrect voltage output (e.g., defaulting to 9V or 5V).
3. Select New Voltage: To set a desired voltage (9V, 15V, or 20V), create a solder bridge between the corresponding voltage pad and the adjacent common pad (usually an outer pin or a designated common point).
4. 5V Output: If all voltage selection pads are left unbridged (i.e., no solder bridges are made after removing the 12V default), the module will typically default to a 5V output, provided the connected power source supports it.
5. Connect Power Source: Plug a compatible USB-C Power Delivery or Quick Charge power source into the module's USB-C port. The power source must support the desired voltage for the module to trigger it.
6. Connect Load: Connect your DC-powered device to the output pads (+ and -) of the module. Ensure correct polarity.

Important Note on Voltage Negotiation:

• The connected USB-C charger or power bank must support the voltage you are attempting to trigger. If the charger does not support the selected voltage, the module will negotiate the highest available voltage that the charger does support (e.g., if 20V is selected but only 9V is available, it will output 9V).
• The module does not limit current. Ensure your connected load has appropriate current limiting or protection to prevent damage to the load or the power source.

Operation

Once the voltage is configured and the module is connected to a compatible USB-C PD/QC power source and your load, it will begin to supply power. A small blue status LED near the USB-C port indicates that the module is powered and operating.

The actual output current and power delivered will be determined by the capabilities of your fast-charging power source and the power requirements of your connected load. The module supports a maximum current of 5A.

This module is ideal for converting modern USB-C PD/QC power sources into versatile DC power supplies for various electronic projects, routers, LED strips, and other devices that traditionally use barrel jack connectors.

Maintenance

The DWEII USB-C PD Trigger Board Module requires minimal maintenance. To ensure longevity and proper function:

• Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the module to moisture, extreme temperatures, or corrosive environments.
• Handle with care to prevent physical damage to the components or solder joints.

Troubleshooting

• No Output Voltage or Incorrect Voltage:
  • Verify that your USB-C power source (charger/power bank) supports the desired voltage. The module will only output voltages that the source can provide.
  • Ensure the default 12V solder bridge (often a tiny resistor) has been completely removed before attempting to set a new voltage.
  • Check your solder connections for the desired voltage setting. Ensure a clean and solid bridge.
  • If no specific voltage is set, the module should default to 5V.
• Power Source Trips or Shuts Down:
  • The module does not limit current. Ensure your connected load does not draw more current than your power source can safely provide. Overcurrent can cause the power source to shut down for protection.
  • Verify that your load is not short-circuited.
• Module Does Not Negotiate Voltage with Battery/Parallel Power:
  • If you have a battery or another power source connected in parallel to the output, the module may not be able to negotiate the voltage correctly. Consider adding a diode to prevent back-feeding power to the module's output during negotiation.
• Blue LED Not Lit:
  • Ensure the USB-C power source is properly connected and supplying power.
  • Check if the power source itself is functioning correctly.
