The TMCM-1043 is a single axis stepper motor controller/driver module for sensorless load dependent current control. The device is powered by Trinamic StallGuard2™, CoolStep™ and SpreadCycle™ chopper technology. The TMCM-1043 is capable of driving up to 1.6A of current from each output (with proper heatsinking). It is designed for an operating voltage of 9...28V. The device provides a S/D interface. With its optional programming TMCM-1043-KIT, the TMCM-1043 becomes a fully customizable smart driver stage allowing for adaption to a broad range of embedded motion control and mechatronics requirements. * 2-phase stepper motor driver board * Step/Dir Interface * On-board Processor for initialization and diagnostic * Fixed Drive Capability 1.1A RMS (1.6A peak current) or * Program. Drive Capability up to 1.4A RMS (2A peak) * Voltage Range 12 to 24V DC nominal (9 to 28V max.) * Microstep Resolution 16 microsteps per full step input
