Overview:

This system integrates compute, power regulation, and sensing capabilities using the ESP32-S2 microcontroller. It is powered through a 5V USB input, which is stepped down to 3.3V using an ST1S08PUR buck converter with added protection from decoupling capacitors and a resettable fuse. An MPU-6500 6-axis IMU communicates with the ESP32-S2 via I2C, enabling real-time motion and orientation tracking. The design supports applications requiring responsive and stable control, such as aerial navigation or robotic motion.

Description:

This project enables real-time motion sensing and processing for embedded control systems. The ESP32-S2 handles computation and I2C communication with the MPU-6500 IMU to gather accelerometer and gyroscope data, allowing for precise movement tracking. The system is powered by a USB input and regulated by an ST1S08PUR buck converter, ensuring safe and reliable 3.3V operation. Designed for responsiveness and stability, the setup is ideal for use in flight control systems, robotics, and other motion-sensitive platforms.
