The following table outlines the key technical specifications of the Micro PD Board - Top:

The Micro PD Board - Top features multiple input and output pins for flexible power distribution. The table below describes the pin configuration:

1. Power Input: Connect the input voltage (5V to 20V DC) to the VIN pin and the ground to the GND pin.
2. Voltage Selection: Use the SEL1 and SEL2 pins to select the desired output voltage for VOUT1 and VOUT2. Refer to the manufacturer's datasheet for the specific logic levels required for voltage selection.
3. Power Outputs: Connect your load to the VOUT1 and/or VOUT2 pins. Ensure the total current draw does not exceed 3A per channel.
4. Enable Pin: Use the EN pin to enable or disable the board. Pull the pin high to enable the board and low to disable it.
5. Mounting: Secure the board in your project using screws or adhesive, ensuring proper ventilation for heat dissipation.

• Input Voltage: Ensure the input voltage is within the specified range (5V to 20V DC) to avoid damaging the board.
• Current Limits: Do not exceed the maximum output current of 3A per channel to prevent overheating or triggering the overcurrent protection.
• Heat Management: If operating at high currents, ensure adequate ventilation or use a heatsink to manage heat dissipation.
• Voltage Selection: Double-check the voltage selection logic before powering the board to avoid incorrect output voltages.
• Polarity: Always connect the input voltage with the correct polarity to prevent damage to the board.

The Micro PD Board - Top can be used to power an Arduino UNO and other peripherals. Below is an example circuit and code:

1. Connect the VIN pin of the Micro PD Board to a 12V DC power supply.
2. Connect the GND pin of the Micro PD Board to the ground of the Arduino UNO.
3. Connect the VOUT1 pin (set to 5V) to the 5V pin of the Arduino UNO.
4. Use the EN pin to control the power delivery to the Arduino UNO.

// Example code to control the EN pin of the Micro PD Board
// This code toggles the power delivery on and off every 2 seconds.

const int enablePin = 7; // Connect EN pin of Micro PD Board to Arduino pin 7

void setup() {
  pinMode(enablePin, OUTPUT); // Set the EN pin as an output
}

void loop() {
  digitalWrite(enablePin, HIGH); // Enable power delivery
  delay(2000); // Wait for 2 seconds
  digitalWrite(enablePin, LOW); // Disable power delivery
  delay(2000); // Wait for 2 seconds
}

1. No Output Voltage:

   • Cause: The EN pin is not pulled high.
   • Solution: Ensure the EN pin is connected to a high logic level to enable the board.

2. Overheating:

   • Cause: Excessive current draw or insufficient ventilation.
   • Solution: Reduce the load current or improve ventilation around the board.

3. Incorrect Output Voltage:

   • Cause: Incorrect voltage selection on SEL1 or SEL2.
   • Solution: Verify the logic levels on the selection pins and adjust as needed.

4. Board Not Powering On:

   • Cause: Input voltage is out of range or connected with incorrect polarity.
   • Solution: Check the input voltage and polarity, ensuring it is within the specified range.

Q1: Can I use the Micro PD Board to power multiple devices simultaneously?
A1: Yes, you can use both VOUT1 and VOUT2 to power multiple devices, provided the total current draw does not exceed 3A per channel.

Q2: What happens if I exceed the maximum current rating?
A2: The board's overcurrent protection will activate, shutting down the output to prevent damage.

Q3: Can I use the board in outdoor applications?
A3: The board is not weatherproof. If used outdoors, ensure it is enclosed in a weather-resistant case.

Q4: How do I select the output voltage?
A4: Use the SEL1 and SEL2 pins to select the desired output voltage. Refer to the datasheet for the specific logic levels required.
