M5Stamp Fly with M5StampS3

The M5Stamp Fly from M5Stack is a programmable open-source quadcopter/drone kit, featuring the StampS3 as the main controller.

It integrates a BMI270 6-axis gyroscope and a BMM150 3-axis magnetometer for altitude and direction detection. The BMP280 barometric pressure sensor and two VL53L3 distance sensors enable precise altitude hold and obstacle avoidance. The PMW3901MB-TXQT optical flow sensor provides displacement detection.

The kit includes a buzzer, a reset button, and WS2812 RGB LEDs for interaction and status indication. It is equipped with a 300mAh high-voltage battery and four high-speed coreless motors. The PCB features an INA3221AIRGVR for real-time current/voltage monitoring and has two Grove connectors for additional sensors and peripherals.

Preloaded with debugging firmware, the M5Stack M5Stamp Fly can be controlled using an Atom Joystick (not included) via the ESP-NOW protocol. Users can choose between automatic and manual modes, allowing for easy implementation of functions like precise hovering and flips. The firmware source code is open-source, making the product suitable for education, research, and various drone development projects.

Important Notes

• Atom Joystick (controller) is required for control and battery charging but is not included.
• When the batteries are depleted, insert the batteries into the charging slot of the Atom Joystick (not included). Connect a USB-C cable to the Atom Joystick to start charging.

Instructions for Use

The following instructions assume the use of the M5Atom Joystick which is not included.

• Pairing
  • Long press the middle button on the AtomS3 to power on, then press again as prompted on the screen to enter pairing mode.
  • Press the reset button on the Stamp Fly to send a pairing broadcast.
  • Wait for pairing to complete.
• Operation
  • Takeoff and Landing
    • Single-click the middle button on the AtomS3 to control takeoff or landing.
  • Control Mode
    • Press the left front button on the Atom Joystick to switch control modes.
    • Stable Mode: Provides stable control interaction, suitable for routine flying and cruising.
    • Sport Mode: Offers maximum control freedom, capable of performing complex maneuvers, requiring high operating skills.
  • Altitude Mode
    • Press the right front button on the Atom Joystick to switch altitude modes.
    • Auto Altitude: Keeps altitude stable at a set value; pushing the left joystick up or down changes the set altitude.
    • Manual Altitude: Full throttle control of altitude, requiring high operating skills.
  • Aerial Stunts
    • Flip: During flight, pressing the center button of the right joystick on the Atom Joystick performs a flip manoeuvre.
