The HuskyLens 2 Power Board features a simple pinout for easy integration with the HuskyLens 2 module and other peripherals.

The HuskyLens 2 Power Board is straightforward to use and integrates seamlessly with the HuskyLens 2 AI camera module. Follow the steps below to set up and use the board:

1. Connect a 5V DC power source to the USB-C port of the power board.
2. Ensure the power source can supply at least 2A to avoid power instability.

1. Use the 4-pin Grove cable to connect the HuskyLens 2 module to the Grove interface on the power board.
2. Ensure the VCC and GND pins are correctly aligned to avoid damage.

1. Use the onboard voltage selection jumper to choose between 3.3V and 5V output.
2. Set the jumper to match the voltage requirements of your connected peripherals.

The HuskyLens 2 Power Board can be connected to an Arduino UNO for AI-based projects. Below is an example code snippet to interface the HuskyLens 2 module with the Arduino UNO:

#include <Wire.h>

// Define the I2C address of the HuskyLens 2 module
#define HUSKYLENS_I2C_ADDRESS 0x32

void setup() {
  Wire.begin(); // Initialize I2C communication
  Serial.begin(9600); // Start serial communication for debugging

  // Check if the HuskyLens 2 module is connected
  Wire.beginTransmission(HUSKYLENS_I2C_ADDRESS);
  if (Wire.endTransmission() == 0) {
    Serial.println("HuskyLens 2 module detected!");
  } else {
    Serial.println("Error: HuskyLens 2 module not detected.");
  }
}

void loop() {
  // Example: Request data from the HuskyLens 2 module
  Wire.requestFrom(HUSKYLENS_I2C_ADDRESS, 6); // Request 6 bytes of data
  while (Wire.available()) {
    char c = Wire.read(); // Read each byte
    Serial.print(c); // Print the received data
  }
  delay(1000); // Wait for 1 second before the next request
}

• Always verify the voltage requirements of your peripherals before connecting them to the power board.
• Use a high-quality USB-C cable and power adapter to ensure stable power delivery.
• Avoid short circuits by carefully aligning the Grove connector pins.

1. HuskyLens 2 module not powering on:

   • Ensure the USB-C power source is providing at least 5V and 2A.
   • Check the Grove cable connection for proper alignment.

2. Peripheral devices not receiving power:

   • Verify the voltage selection jumper is set to the correct output voltage (3.3V or 5V).
   • Inspect the Grove cable for any damage or loose connections.

3. I2C communication errors:

   • Confirm the SDA and SCL lines are correctly connected.
   • Check for address conflicts if multiple I2C devices are connected.

Q: Can I use a battery pack to power the HuskyLens 2 Power Board?
A: Yes, as long as the battery pack provides a stable 5V output via USB-C and can supply at least 2A.

Q: Is the power board compatible with other Grove modules?
A: Yes, the Grove interface on the power board can be used with other Grove-compatible modules, provided they operate at 3.3V or 5V.

Q: How do I know if the power board is working correctly?
A: The onboard LED indicator will light up when the board is powered and functioning properly.

By following this documentation, you can effectively use the HuskyLens 2 Power Board in your projects and troubleshoot any issues that may arise.
