Description M5Stack M5Stamp Fly v1.1 is a programmable open-source quadcopter kit upgraded with the Stamp-S3A main controller. Compared with the earlier StampFly, M5Stack M5Stamp Fly v1.1 improves the antenna structure for stronger wireless reception and a more stable remote connection, while keeping the compact educational drone form factor for STEM learning, research experiments, and embedded flight development. The M5Stack M5Stamp Fly v1.1 platform integrates a BMI270 6-axis attitude sensor, BMM150 3-axis magnetometer, BMP280 pressure sensor, two VL53L3C distance sensors, INA3221AIRGVR current and voltage monitoring, a buzzer, WS2812 RGB LED, and two Grove expansion interfaces. When paired with the Atom Joystick remote controller, M5Stack M5Stamp Fly v1.1 communicates through ESP-NOW and supports manual flight, automatic flight, fixed-point hovering, and aerial flips. Features Stamp-S3A controller: M5Stack M5Stamp Fly v1.1 uses Stamp-S3A with an ESP32-S3 dual-core processor for programmable flight control. Improved wireless structure: optimized antenna design helps M5Stack M5Stamp Fly v1.1 maintain a more stable connection than the earlier StampFly design. Multi-sensor flight system: includes BMI270 attitude sensing, BMM150 direction detection, BMP280 pressure detection, and VL53L3C distance sensing. Altitude hold and obstacle support: two VL53L3C sensors help with precise altitude hold and intelligent obstacle avoidance workflows. Power monitoring: INA3221AIRGVR monitors real-time voltage and current for the quadcopter system. Interactive feedback: onboard 5020 passive buzzer and WS2812 RGB LED provide status indication. Expandable hardware: two Grove interfaces support additional sensors and peripherals for M5Stack M5Stamp Fly v1.1 projects. Open-source development: firmware source code is available for secondary development and customized flight functions.
