Key Features:

• Main Controller: M5StampS3 with ESP32-S3 microcontroller, offering advanced features such as WiFi and OTG/CDC support.
• Integrated Sensors:
  • BMI270 6-axis gyroscope and BMM150 3-axis magnetometer for attitude and direction detection.
  • BMP280 barometric pressure sensor for precise altitude hold.
  • Two VL53L3 distance sensors for obstacle avoidance.
  • PMW3901MB-TXQT optical flow sensor for hovering and displacement detection.
  • INA3221AIRGVR for real-time current/voltage monitoring.
• Power System: 300mAh high-voltage lithium battery and four high-speed coreless motors.
• Interactive Elements: Built-in passive buzzer for audio feedback, WS2812 RGB LEDs for status indication, and a reset button.
• Expansion: Two Grove connectors for additional sensors and peripherals, enabling extensive customization.
• Control: Preloaded with debugging firmware, controllable via ESP-NOW protocol (e.g., with M5Atom Joystick). Supports automatic and manual flight modes.
• Open-Source: Firmware source code is open-source, facilitating learning and development.

Setup Guide

1. Unboxing and Inspection

Carefully remove all components from the packaging. Verify that all items listed in the product description are present and undamaged. The kit includes the M5Stamp Fly drone and a 300mAh lithium battery.

2. Battery Installation and Charging

• Locate the battery connector on the M5Stamp Fly.
• Connect the provided 300mAh lithium battery to the drone's battery port. Ensure the polarity is correct.
• Before first use, fully charge the battery using a compatible USB charger connected to the drone's USB-C port. The charging indicator (if present, typically an LED) will change status upon full charge.

3. Initial Power On and Firmware Check

• Once the battery is connected, the drone should power on. Observe the WS2812 RGB LEDs for initial status indications.
• The M5Stamp Fly comes preloaded with debugging firmware. For advanced development or custom firmware, refer to the official M5Stack documentation and GitHub repositories for flashing instructions.

4. Connecting to a Controller (e.g., M5Atom Joystick)

• If using an M5Atom Joystick (sold separately), ensure it is also powered on and configured for ESP-NOW communication.
• Follow the pairing instructions provided with your M5Atom Joystick to establish a connection with the M5Stamp Fly. This typically involves a specific button sequence or software configuration.

Operating Instructions

1. Pre-Flight Checklist

• Ensure the battery is fully charged.
• Verify all propellers are securely attached and free from damage.
• Confirm the flight area is clear of obstacles and people.
• Ensure the M5Stamp Fly and your controller are properly paired and communicating.

2. Flight Modes

The M5Stamp Fly supports both automatic and manual flight modes, depending on the loaded firmware and controller capabilities.

• Automatic Mode: Utilizes integrated sensors (VL53L3 for distance, BMP280 for altitude, PMW3901MB-TXQT for optical flow) to assist with stable hovering, altitude hold, and obstacle avoidance. This mode is ideal for beginners or for precise maneuvers like flips.
• Manual Mode: Provides direct control over the drone's movements, relying more on user input. This mode is suitable for experienced users or for custom flight patterns.

3. Basic Flight Controls (with M5Atom Joystick example)

While specific controls may vary based on firmware and controller, typical drone controls include:

• Throttle (Vertical Movement): Typically controlled by the left joystick (up/down).
• Yaw (Rotation): Typically controlled by the left joystick (left/right).
• Pitch (Forward/Backward): Typically controlled by the right joystick (up/down).
• Roll (Left/Right Sideways Movement): Typically controlled by the right joystick (left/right).
• Take-off/Landing: Often a dedicated button or a specific joystick combination.
• Flips/Special Maneuvers: Activated via specific button presses or joystick movements in automatic mode.

Always refer to the specific documentation for the firmware loaded on your M5Stamp Fly and your chosen controller for detailed control mapping.

4. Sensor Utilization

• VL53L3 Distance Sensors: Used for obstacle detection and avoidance. The drone can be programmed to automatically adjust its flight path when an obstacle is detected within a certain range.
• BMP280 Barometric Pressure Sensor: Provides accurate altitude readings, enabling stable altitude hold functionality.
• PMW3901MB-TXQT Optical Flow Sensor: Essential for precise hovering and displacement detection, especially in indoor environments where GPS signals are unavailable.

Maintenance

1. Battery Care

• Always use the recommended charging method.
• Do not overcharge or over-discharge the battery.
• Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
• If the battery swells or shows signs of damage, discontinue use immediately and dispose of it properly.

2. Propeller Inspection and Replacement

• Regularly inspect propellers for cracks, bends, or chips. Damaged propellers can affect flight stability and efficiency.
• To replace a propeller, gently pull the old one off the motor shaft and push a new one firmly into place. Ensure the correct propeller type (clockwise/counter-clockwise) is installed on the correct motor.

3. Cleaning

• Use a soft, dry cloth to clean the drone's body and components.
• Avoid using liquid cleaners or solvents, as they may damage electronic components.
• Gently remove any dust or debris from sensors and motor areas using a soft brush or compressed air.

4. Firmware Updates

Periodically check the official M5Stack website or GitHub repository for firmware updates. Updates can improve performance, add new features, or fix bugs. Follow the provided instructions carefully when performing firmware updates.
