The core improvement is the main control module upgraded from Stamp-S3 to the more powerful Stamp-S3A, with a newly optimized antenna structure design that significantly enhances wireless signal reception performance, resulting in a more stable remote connection. The drone integrates a BMI270 six-axis gyroscope and a BMM150 three-axis magnetometer for accurate attitude and orientation detection. Paired with a BMP280 pressure sensor and two VL53L3 distance sensors, it achieves stable precise altitude hold and intelligent obstacle avoidance. Onboard buzzer, reset button, and WS2812 RGB LED are used for human-machine interaction and device status indication. It comes with a 300mAh high-voltage battery and four high-speed coreless motors, providing ample power output. An onboard INA3221AIRGVR chip monitors real-time current and voltage. Two Grove expansion interfaces are reserved for flexible connection of various sensors and peripherals. The product is pre-loaded with a debugging program. When used with the Atom Joystick remote controller, it establishes wireless communication via the ESP-NOW protocol, supporting both manual and automatic flight modes, enabling features like fixed-point hovering and aerial flips. The complete firmware source code is open-source, facilitating secondary development and feature customization. It is suitable for STEM education, scientific research experiments, drone project development, and embedded learning training. Charging Notice Connect the battery to the charging slot of the Atom Joystick, then connect the data cable to the Atom Joystick to start charging. Battery Maintenance 1. Do not discharge the battery below 3V per cell under load.2. Do not store a fully charged battery for more than 3 days. For long-term storage, keep the voltage between 3.8V and 3.9V.
