Onboard serial bus servo interfaces for controlling up to 253 ST3215 serial bus servos and obtaining servo feedback. This enables scalable, multijoint robotics with centralized servo management and realtime status reporting. Onboard motor control interfaces for 2x DC motors with encoders or 4x DC motors (2 groups) without encoders. Provides flexible drive options to match different robot designs, offering closedloop control when encoders are present and simplified wiring when they are not. Based on the ESP32WROOM32 module, supports wireless communication such as WiFi, Bluetooth and ESPNOW. Facilitates remote control, telemetry, and integration with other devices and systems without wired connections. Onboard 9DOF IMU to obtain attitude and heading information at any time. Supports reliable orientation, motion sensing, and sensor fusion for navigation, stabilization, and pose estimation. Use scenarios and applications Robotic arms and manipulators: Manage many servo joints with feedback for precise positioning, coordinated motion, and scalable configurations in compact form factors. Autonomous mobile robots and platforms: Combine encoderequipped DC motors for accurate speed and position control with IMU data for reliable pose estimation and stable navigation. Teleoperation and remote monitoring: Leverage WiFi, Bluetooth, or ESPNOW to control, monitor, and exchange data with the system from a distance, enabling flexible field operation and remote diagnostics.
