The K230 Vision Module features a 10-pin interface for easy integration. Below is the pinout and description:

The K230 Vision Module is designed for straightforward integration into various systems. Follow the steps below to use the module effectively:

1. Power Supply: Connect the VCC pin to a 5V DC power source and the GND pin to ground.
2. Communication Interface: Choose a communication protocol (UART, I2C, or SPI) based on your application:
   • For UART, connect the TX and RX pins to the corresponding pins on your microcontroller.
   • For I2C, connect the SCL and SDA pins to the I2C bus of your microcontroller.
   • For SPI, connect CS, MOSI, MISO, and SCK to the respective SPI pins on your microcontroller.
3. Optional USB Connection: Use the USB interface for direct connection to a PC for testing or firmware updates.

The following example demonstrates how to interface the K230 Vision Module with an Arduino UNO using UART communication.

// Include necessary libraries
#include <SoftwareSerial.h>

// Define RX and TX pins for SoftwareSerial
SoftwareSerial K230Serial(10, 11); // RX = Pin 10, TX = Pin 11

void setup() {
  // Initialize serial communication with the K230 Vision Module
  K230Serial.begin(115200); // Set baud rate to 115200
  Serial.begin(9600);       // For debugging via Serial Monitor

  // Notify user that setup is complete
  Serial.println("K230 Vision Module Initialized");
}

void loop() {
  // Check if data is available from the K230 Vision Module
  if (K230Serial.available()) {
    // Read data from the module
    String data = K230Serial.readString();
    
    // Print the received data to the Serial Monitor
    Serial.println("Data from K230: " + data);
  }

  // Optional: Send commands to the K230 Vision Module
  if (Serial.available()) {
    String command = Serial.readString();
    K230Serial.println(command); // Send command to the module
  }
}

• Ensure the module is powered with a stable 5V DC supply to avoid damage.
• Use level shifters if interfacing with a 3.3V microcontroller.
• Avoid placing the module in direct sunlight or extremely dusty environments for optimal performance.
• Regularly update the firmware to access the latest features and improvements.

1. No Data Received from the Module

   • Cause: Incorrect baud rate or wiring.
   • Solution: Verify the baud rate (default is 115200) and check the connections.

2. Module Not Powering On

   • Cause: Insufficient power supply.
   • Solution: Ensure the power source provides a stable 5V DC with at least 500mA current.

3. Unstable or Noisy Data

   • Cause: Electrical interference or poor grounding.
   • Solution: Use shorter wires and ensure proper grounding.

4. Firmware Update Fails

   • Cause: Interrupted connection during the update process.
   • Solution: Reconnect the module and restart the update process.

Q1: Can the K230 Vision Module detect multiple objects simultaneously?
A1: Yes, the module supports multi-object detection and tracking, depending on the processing algorithm used.

Q2: Is the module compatible with Raspberry Pi?
A2: Yes, the K230 Vision Module can be connected to Raspberry Pi via UART, I2C, or SPI.

Q3: What is the maximum cable length for communication?
A3: For UART and I2C, keep the cable length under 1 meter to avoid signal degradation. For SPI, shorter cables (less than 50cm) are recommended.

Q4: Can the module operate outdoors?
A4: The module can operate outdoors but should be protected from direct sunlight, rain, and extreme temperatures.
