Circuit Documentation
Summary of the Circuit
This circuit integrates an ESP32 microcontroller with a BNO055 intelligent 9-axis absolute orientation sensor. The ESP32 serves as the central processing unit, capable of handling various tasks and interfacing with the BNO055 sensor to obtain orientation data. The BNO055 is directly connected to the ESP32 via I2C communication protocol, which uses two lines: SDA (data line) and SCL (clock line). Power is supplied to both components through a 3.3V connection, and a common ground is established to complete the circuit.
