4. Setup Guide

This section outlines the general steps for setting up your Cube Kore carrier board. Ensure you have the Pixhawk 2.1 Cube and all necessary multirotor components before proceeding.

4.1. Board Overview

Figure 4.1: Cube Kore Carrier Board (top view with Cube placeholder).

The Cube Kore board is designed for easy integration. The central square area is where the Pixhawk 2.1 Cube module securely mounts. Surrounding this area are various connectors for ESCs, power, and peripherals.

Figure 4.2: Cube Kore Carrier Board (bottom view).

The bottom of the board houses the built-in buzzer, control buttons, and additional components for power management and signal processing.

4.2. Mounting the Pixhawk 2.1 Cube

1. Carefully align the Pixhawk 2.1 Cube with the central connector on the Kore carrier board.
2. Gently press the Cube down until it is firmly seated. Ensure all pins are correctly aligned to prevent damage.
3. Secure the Cube using the provided mounting hardware (if applicable, typically part of the Cube package).

4.3. Connecting ESCs and Motors

The Kore board features dedicated power and signal pads at each corner for connecting Electronic Speed Controllers (ESCs). These are designed for multirotor configurations up to 8 arms.

1. Connect the power leads of each ESC to the corresponding power pads (positive and negative) on the Kore board. Ensure correct polarity.
2. Connect the signal wire of each ESC to the designated PWM signal pin for that motor output. Refer to your flight controller's documentation for specific motor assignments.
3. Connect the motor wires to the ESCs according to your motor's rotation direction requirements.

4.4. Power Supply Connection

The Kore board supports up to 12-cell Lithium batteries (50.4V) and handles high continuous and surge currents.

1. Connect your main flight battery (e.g., via XT60 connector) to the designated main power input on the Kore board.
2. Ensure the battery voltage is within the supported range (up to 50.4V).

4.5. Peripheral Connections

The Kore board provides various ports for connecting essential peripherals:

• GPS/Compass: Use the provided GPS cables to connect your GPS and compass modules to the designated ports (GPS1, GPS2).
• Telemetry: Connect your telemetry radio using the Telem cable.
• I2C: Use the I2C cable and I2C board for connecting I2C peripherals like external compasses or airspeed sensors.
• CAN: Connect CAN bus devices using the CAN cable.
• Payload Power: Utilize the 5V, 12V, and direct battery payload power connectors with resettable fuses for cameras, gimbals, or other accessories.
• USB: Connect the Micro USB cable to the board for configuration and firmware updates via your flight controller software.

5. Operating Instructions

The Cube Kore board acts as a power distribution and signal routing hub for the Pixhawk 2.1 Cube. Its operation is largely dependent on the configuration and firmware of the Pixhawk Cube itself.

5.1. Powering On

1. Ensure all connections are secure and correct.
2. Connect the main flight battery to the Kore board.
3. Observe the indicator lights on the Kore board and the Pixhawk Cube. A solid green light typically indicates stable power.
4. Listen for the initialization tones from the built-in buzzer, indicating the Pixhawk Cube is booting up.

5.2. System Status Indicators

• Power Indicator: A dedicated LED indicates the status of the main power supply.
• Error Indicator: An LED will illuminate or flash to indicate system errors or warnings. Consult the Pixhawk Cube documentation for specific error codes.
• Buzzer: Provides audible feedback for system status, arming/disarming, and warnings. The volume can be adjusted.

5.3. PWM Voltage Selection

The Kore board allows selection of PWM signal voltage (3.3V or 5V) to match your ESCs or other PWM-controlled devices. Refer to the board's markings or the official documentation for the location of the voltage selector jumper or switch.

Caution: Ensure the selected voltage matches the requirements of your connected devices to prevent damage.

6. Maintenance

Proper maintenance ensures the longevity and reliability of your Cube Kore board.

• Regular Inspection: Periodically inspect the board for any signs of physical damage, loose connections, or corrosion.
• Cleaning: Keep the board clean and free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids or solvents.
• Storage: When not in use, store the board in a dry, anti-static environment, away from extreme temperatures.
• Connection Integrity: Ensure all cables and connectors are securely seated and free from strain.
