How to Use Copernicus II DIP Module: Examples, Pinouts, and Specs

The Copernicus II DIP Module is a compact, high-performance GPS receiver with an integrated antenna designed for a broad spectrum of OEM applications. It is capable of providing precise position and time information. Common applications include asset tracking, navigation devices, time synchronization, and location-based services.

• Receiver Type: 12-channel, L1 frequency band GPS receiver
• Update Rate: Up to 10 Hz
• Sensitivity: -160 dBm tracking, -142 dBm acquisition
• Time to First Fix: 29 seconds (cold start), 1 second (hot start)
• Operating Voltage: 2.7V to 3.6V
• Power Consumption: 44 mA at 3.3V (typical)
• Operating Temperature: -40°C to +85°C
• Dimensions: 19.2 mm x 19.2 mm x 2.5 mm

1. Power Supply: Connect the VCC pin to a clean, regulated 3.3V power source. Ensure that the power supply can deliver sufficient current for the module's operation.
2. Grounding: Connect the GND pin to the system ground.
3. Serial Communication: Connect the TX and RX pins to a microcontroller or another serial device for data communication. Remember to cross-connect TX to RX and RX to TX.
4. Power Control: If you wish to control the power state of the module, connect the ON/OFF pin to a digital output on your microcontroller.
5. Reset: The RESET pin can be connected to a microcontroller or left unconnected if not used.
6. PPS Output: The PPS pin outputs a pulse per second, which can be used for precise timing applications.

• Ensure that the antenna has a clear view of the sky for optimal performance.
• Avoid placing the module near sources of RF interference.
• Use short and direct connections to the power supply to minimize voltage drops.
• Implement proper decoupling capacitors close to the module's power supply pins to filter out noise.

#include <SoftwareSerial.h>

SoftwareSerial gpsSerial(10, 11); // RX, TX

void setup() {
  // Start the serial communication with the host computer
  Serial.begin(9600);
  while (!Serial) {
    ; // Wait for serial port to connect.
  }

  // Start communication with the GPS module
  gpsSerial.begin(4800);
  Serial.println("GPS Module Copernicus II DIP started");
}

void loop() {
  // Check if data is available from the GPS module
  if (gpsSerial.available()) {
    // Forward the data from the GPS module to the host computer
    Serial.write(gpsSerial.read());
  }

  // Check if data is available from the host computer
  if (Serial.available()) {
    // Forward the data from the host computer to the GPS module
    gpsSerial.write(Serial.read());
  }
}

• No GPS Fix: Ensure the antenna has a clear view of the sky. Check for any obstructions or interference sources.
• No Data Output: Verify the baud rate and wiring connections between the GPS module and the microcontroller.
• Intermittent Signal: Check for loose connections and ensure the power supply is stable and within the specified voltage range.

• Power Issues: Use a multimeter to check the voltage at the VCC pin. It should be between 2.7V and 3.6V.
• Signal Quality: Place the module away from tall buildings, trees, and other obstructions.
• Data Communication: Ensure that the serial communication parameters (baud rate, data bits, etc.) match between the GPS module and the microcontroller.

Q: Can I use an external antenna with the Copernicus II DIP Module? A: The module comes with an integrated antenna, but it also supports an external antenna if needed.

Q: What is the default baud rate for the Copernicus II DIP Module? A: The default baud rate is 4800 bps.

Q: How can I change the update rate of the GPS module? A: The update rate can be configured using proprietary configuration commands. Refer to the module's datasheet for detailed instructions.

Q: Is the Copernicus II DIP Module waterproof? A: The module itself is not waterproof. It should be housed in a waterproof enclosure if used in outdoor environments.
