How to Use USB-C PD Trigger Board Module: Examples, Pinouts, and Specs

The USB-C PD Trigger Board Module (Manufacturer: Dewlawn, Part ID: USBCtester5-1118) is a versatile electronic component designed to facilitate power delivery (PD) negotiation over USB-C connections. This module enables devices to request specific voltage and current levels from a USB-C power source, making it ideal for applications requiring adjustable power management.

Common applications include:

• Prototyping and testing USB-C power delivery capabilities
• Powering devices with specific voltage and current requirements
• Battery charging circuits with adjustable power input
• USB-C power delivery education and experimentation

The following table outlines the key technical details of the USB-C PD Trigger Board Module:

The module features the following pins for interfacing:

1. Connect the USB-C Power Source: Plug a USB-C power adapter into the module's USB-C port. Ensure the adapter supports the desired voltage and current levels.
2. Set the Output Voltage: Use the SEL1 and SEL2 pins to configure the desired output voltage:
   • SEL1 = LOW, SEL2 = LOW: 5V
   • SEL1 = HIGH, SEL2 = LOW: 9V
   • SEL1 = LOW, SEL2 = HIGH: 12V
   • SEL1 = HIGH, SEL2 = HIGH: 20V
3. Enable the Module: Pull the EN pin HIGH to activate the module and initiate power delivery negotiation.
4. Connect the Load: Attach the device or circuit to the VOUT and GND pins to receive the negotiated power.

• Ensure the USB-C power source can supply the required voltage and current for your application.
• Use appropriate heat dissipation methods if operating at high power levels (e.g., 20V @ 3A).
• Avoid shorting the VOUT and GND pins, as this may damage the module or power source.
• For safety, verify the output voltage with a multimeter before connecting sensitive devices.

The USB-C PD Trigger Board Module can be used to power an Arduino UNO. Below is an example of how to configure the module for 9V output and connect it to the Arduino:

• Connect the module's VOUT pin to the Arduino's VIN pin.
• Connect the module's GND pin to the Arduino's GND pin.
• Set SEL1 = HIGH and SEL2 = LOW to configure the output voltage to 9V.
• Pull the EN pin HIGH to enable the module.

The following code demonstrates how to control the SEL1 and SEL2 pins using the Arduino:

// Define pin connections for SEL1 and SEL2
const int SEL1_PIN = 7; // Connect SEL1 to Arduino digital pin 7
const int SEL2_PIN = 8; // Connect SEL2 to Arduino digital pin 8

void setup() {
  // Set SEL1 and SEL2 as output pins
  pinMode(SEL1_PIN, OUTPUT);
  pinMode(SEL2_PIN, OUTPUT);

  // Configure the module for 9V output
  digitalWrite(SEL1_PIN, HIGH); // Set SEL1 to HIGH
  digitalWrite(SEL2_PIN, LOW);  // Set SEL2 to LOW
}

void loop() {
  // The module will maintain the configured voltage
  // No additional code is required in the loop
}

1. No Output Voltage

   • Cause: The EN pin is not pulled HIGH.
   • Solution: Ensure the EN pin is connected to a HIGH signal to enable the module.

2. Incorrect Output Voltage

   • Cause: SEL1 and SEL2 pins are not configured correctly.
   • Solution: Verify the SEL1 and SEL2 pin states match the desired voltage configuration.

3. Module Overheating

   • Cause: Excessive current draw or insufficient heat dissipation.
   • Solution: Ensure the load does not exceed the module's maximum current rating (3A). Use a heatsink if necessary.

4. Power Source Not Recognized

   • Cause: The USB-C power adapter does not support the requested voltage/current.
   • Solution: Use a USB-C power adapter that supports the desired PD profile.

Q: Can this module be used with non-PD USB-C power sources?
A: No, the module requires a USB-C power source that supports Power Delivery (PD) for voltage negotiation.

Q: What happens if the load exceeds 3A?
A: The module may enter a protection mode or shut down to prevent damage. Always ensure the load stays within the specified limits.

Q: Can I use this module to power multiple devices simultaneously?
A: Yes, but ensure the total current draw does not exceed 3A, and the devices are compatible with the negotiated voltage.

Q: Is the module compatible with USB-C PD 3.1?
A: The module supports USB-C PD 2.0/3.0. Compatibility with PD 3.1 features is not guaranteed.
