Features: Brand new and high quality Compared to the TMC2209 driver, the current is high and the heat dissipation is better In the case of high-speed printing (with the same current), the motor torque controlled by TMC2240 is greater and more powerful This is an intelligent silence stepper motor drive module The product is made from high-quality materials, with stable performances and long service life In the high-speed modes, the current change amplitudes is very small to maintain sufficient torque Specifications: Material:Plastic Input voltage: DC4.5-36V (recommended: DC12-24V) Wiring method: plug-in drive Logics voltage: 3.3V-5V Package Includes: 1x Stepper Driver Module note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
