The TMC4671-BOB is an evaluation and demonstration board featuring Trinamic\'s TMC4671, a motion controller providing precise torque, current, and velocity control of three-phase brushless DC motors. The board is designed to demonstrate the performance of the TMC4671, allowing engineers to evaluate the processor and its hardware components for development of industrial motion control applications. This board was designed to integrate into a standard 34 x 34 mm QFN24 housing and to be used in a variety of applications, including drive systems, pumps, actuators, and robotics.

The TMC4671-BOB\'s working principle is based on the TMC4671 motor controller\'s ability to use powerful FOC algorithms and current sensing techniques to keep the employed motors\' speed and torque accurately constant. The board features 4 control loops, current, velocity, position, and torque, which are user-selectable and can be used together to implement a complete motion control system for 3-phase brushless motors. The board provides 2 available CAN interfaces, dual encoder ports, separate TTL inputs for controlling direction, step, and limit switching, a diagnostic LED and push-button, and a security switch.

The board\'s special features make it ideal for evaluation, demonstration, and development of industrial applications, motor control systems, and automation projects. The board is suitable for developers who need equipment that has access to external hardware and software control. It allows the user to connect external equipment and programs, such as a PC or another evaluation board, to reprogram, debug, and test the application. Other features include 3 CAN interfaces, allowing up to 8 daisy chained motion controllers, 6 temperature sensors, dual encoder ports, several digital and analog inputs, and configurable limit switches.

In conclusion, the TMC4671-BOB is an evaluation and demonstration board fully featuring the powerful TMC4671 motor controller and offering a comprehensive set of features for evaluation, development, and testing of motion control applications. The board provides several powerful control loops, appropriate interfaces and ports, and several security features, making it ideal for developing industrial motor control applications, drive systems, and robotics.
