K138 M5Stamp Fly with M5StampS3

M5Stamp Fly is a programmable open-source quadcopter kit with the StampS3 as the main controller. It integrates a BMI270 6-axis gyroscope and a BMM150 3-axis magnetometer for attitude and direction detection. The BMP280 barometric pressure sensor and two VL53L3 distance sensors enable precise height maintenance and obstacle avoidance. The PMW3901MB-TXQT optical flow sensor enables the detection of displacements. The kit includes a buzzer, 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. On the PCB is an INA3221AIRGVR for real-time current/voltage monitoring and two Grove connectors for additional sensors and peripherals. The Stamp Fly is pre-installed with debugging firmware and can be controlled with an Atom joystick via the ESP-NOW protocol. The user can choose between an automatic and a manual mode, allowing easy implementation of functions such as precise hovering and flips. The firmware source code is open source, making the product suitable for education, research and various drone development projects.
