2.1 Pinout Diagram

The module features a SH1.0-6Pin connector for easy integration. Refer to the pinout diagram below for correct wiring.

Figure 2.2: Pinout diagram for the M10QMC-5-8-83L GPS Module. This diagram illustrates the function of each pin on the SH1.0-6Pin connector, including VCC, TX, RX, GND, SDA, and SCL.

• VCC: Power input (typically 5V).
• TX: Transmit data (GPS data output).
• RX: Receive data (GPS configuration input).
• GND: Ground connection.
• SDA: I2C Data line (for compass).
• SCL: I2C Clock line (for compass).

2.2 Indicator Lights

The module is equipped with two indicator lights to provide status feedback:

• Power Indicator (Red): Illuminates when the module receives power.
• Positioning Indicator (Green): Flashes when a GPS fix is acquired. A solid light indicates no fix or searching for satellites.

3. Setup

3.1 Wiring

Connect the GPS module to your flight controller using the provided SH1.0-6Pin cable. Ensure correct pin alignment as shown in the diagram below. Incorrect wiring can damage the module or flight controller.

Figure 3.1: Wiring diagram showing connections between the GPS module and a flight controller (FC). This diagram illustrates how each pin (VCC, TX, RX, GND, SDA, SCL) on the GPS module connects to corresponding pins on the flight controller.

1. Connect VCC on the GPS module to a 5V power output on your flight controller.
2. Connect GND on the GPS module to a Ground pin on your flight controller.
3. Connect TX on the GPS module to an available RX UART pin on your flight controller.
4. Connect RX on the GPS module to an available TX UART pin on your flight controller.
5. Connect SDA on the GPS module to the SDA pin of the I2C bus on your flight controller.
6. Connect SCL on the GPS module to the SCL pin of the I2C bus on your flight controller.

Note: Refer to your flight controller's manual for specific UART and I2C pin assignments.

3.2 Mounting

Mount the GPS module securely on your RC vehicle. For optimal performance, consider the following:

• Clear Sky View: Position the module with a clear, unobstructed view of the sky. Avoid placing it directly under carbon fiber plates or other materials that can block GPS signals.
• Interference: Keep the GPS module away from high-current wires, ESCs, VTXs, and other electronic components that can generate electromagnetic interference.
• Orientation: Ensure the module is mounted with the arrow or designated front facing forward relative to your vehicle's flight direction for accurate compass readings.

4. Operating Instructions

4.1 Power On and Initial Status

Upon powering your RC vehicle, the red power indicator on the GPS module will illuminate. The green positioning indicator will initially be solid or off, indicating that the module is searching for satellites.

4.2 GPS Signal Acquisition

For optimal signal acquisition, operate the vehicle in an open outdoor area with a clear view of the sky. The module will begin searching for satellite signals. This process may take a few seconds (hot start) to several minutes (cold start) depending on the environment and previous usage.

• Once a sufficient number of satellites are acquired for a 3D fix, the green positioning indicator will begin to flash. This indicates that the GPS module is providing accurate position data.
• The 10 Hz refresh rate ensures rapid updates of position data to your flight controller.
• The integrated QMC5-8-83L magnetometer will provide heading information to the flight controller, which is essential for features like RTH (Return To Home) and GPS hold modes.

5. Maintenance

The FlyFishRC M10QMC-5-8-83L GPS module is designed for durability. Minimal maintenance is required:

• Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or solvents.
• Physical Inspection: Periodically check the wiring and connections for any signs of wear or damage. Ensure the module remains securely mounted.
• Storage: When not in use, store the module in a dry, cool environment, away from direct sunlight and extreme temperatures.
