Meet the Axion Drive M-41: an all-in-one, open-source controller from Axion Motion. With an onboard trajectory planner and PID feedback, achieve unparalleled precision for your next project.
Onboard STM32C0 runs a high-frequency PID loop and trajectory planner, freeing up your main controller.
Operates from 5V to 45V and delivers up to 4.1A of current, handling a wide range of DC motors.
Control the Axion Drive via I2C or UART with intuitive text commands for quick integration.
Qwiic connectors enable daisy-chaining up to 256 units on one I2C bus, perfect for multi-axis robots.
The embedded trapezoidal trajectory generator eliminates jerky movements by precisely controlling acceleration and deceleration. This reduces mechanical stress and ensures your system moves with stability and grace.
Built on a professionally routed PCB, the Axion Drive is optimized for thermal performance and signal integrity. The clean layout and high-quality components reflect a commitment to reliability and engineering excellence.
The Axion Drive features two Qwiic-compatible connectors, making it simple to create powerful, multi-axis systems. Daisy-chain up to 256 drives on a single I2C bus with minimal wiring, allowing you to build complex robots and machines without the typical cable mess.
