TMC2130 V1.1 Stepper Motor Driver Module can be used separately or in combination with a CNC shield or 3D printer. This V1.1 has the SPI pins soldered upwards so that they are accessible from above.  These Stepper Drivers offer high-efficiency noiseless operations at variable loads, with a full complement of extra features too! Note: The motor direction is reversed with respect to the A4988 and DRV8825 based drivers. You can make changes to the software or mirror the motor pins (hardware). Features: Two-phase stepper motor single-phase current 1.2A (peak 2.5A) motor current can be adjusted Only SPI support Broken down into 256 Combines maximum efficiency and best motor torque for noiseless operation. High-precision sensorless motor load detection. Reduce energy consumption by 75%. High-load drive without out-of-step. Package Includes: 1 x TMC2130 V1.1 stepper motor driver. 1 x Heat Sink. 1x Screwdriver. SKU: PGI-00699622 Category: Motor Driver
