The CLN motor driver series is an **open-source** project aimed at creating a range of compact, cost-efficient high-performance closed-loop stepper drivers for various NEMA form factor motors. These drivers are designed to provide silent and smooth motion, high-precision position control, and energy-saving capabilities, suitable for a wide array of applications in robotics, CNC machines, 3D printers, and more.

## Key Features

- 🕹️ **Closed-Loop Control:** Integrates an encoder for real-time position monitoring, ensuring precise and safe motion.

- 📏 **Fine Positioning:** Achieves high position control accuracy of 0.01° for smooth operation.

- 🛡️ **Reliable Operation and Enhanced Safety:** Features integrated diagnostic and protection mechanisms for the motor and the user safety.

- 🧩 **Modular Concept:** Offers various configurations for different cost, size and performance needs, supporting expansion boards and daisy chain connections.

## Applications

- 🎓 Learning Platforms

- 🛠️ CNC Machines & 3D printers

- 🤖 Robotics & Automation Systems

- 🤝 Collaborative Robots

- 🔭 Camera & Telescope Stabilization Systems

- 🔬 Laboratory Equipment

- 🏭 Industrial Motion Control Systems

- 📳 Haptics & Force Feedback Systems
