Gearotons M17 open-source hardware servomotor integrates the four parts of a motion axis into one standard NEMA-17 body with no protrusions: the motor, the driver, the motion controller, and the encoder. This level of integration enables it to be low-cost ($20 and up) and easier to use. The user has nothing to source and match, nothing to wire between boards, and nothing to configure. Just connect power and one data cable, and you’re good to go. Gearotons M17 specifications: MCU – ST STM32G0 Arm Cortex-M0+ microcontroller Single device with motor, motor driver, motion control system, and encoder Motor control highlights High-precision closed-loop control with built-in encoder and PID control loop that runs at 32 kHz Higher power efficiency in closed-loop control vs. conventional stepper Up to 560 RPM Torque-to-weight ratio is the same as an equivalent stepper motor 64-bit unique ID and a one-byte alias per motor Four models M17‑60 [...]
