Shenzhen Mingjiada Electronics Co., Ltd. offers the ADI TMCM-1290-EVAL evaluation board from stock. This board enables independent assessment of the TMCM-1290 motor controller/driver's characteristics.
Product Overview
The TMCM-1290-EVAL is an evaluation kit based on the TMCM-1290 module, primarily designed for assessing, testing, and validating the module's performance. The TMCM-1290 module itself is a highly integrated single-axis controller and driver specifically engineered for two-phase stepper motors. This evaluation board significantly reduces workload during the prototyping phase by providing extensive interfaces and configuration options.
Core control and drive functionality is implemented by the TMC5240 motion controller and motor driver. This chip supports advanced technologies including StealthChop2, SpreadCycle, StallGuard2, and CoolStep, enabling dynamic current control to ensure quiet, smooth, and efficient motor operation.
Core Features
The TMCM-1290-EVAL evaluation board integrates all advanced capabilities of the TMCM-1290 module, including:
High-performance motor drive: Supports two-phase bipolar stepper motors with coil currents up to 2.1A RMS (3A peak), operating within a supply voltage range of 12V to 31V DC
Multi-protocol communication: Integrated RS485 and SPI interfaces, optional UART, supporting TMCL™ and Modbus protocol stacks for seamless integration into existing control systems
Advanced motion control algorithms:
StealthChop2™: Enables silent, smooth stepper motor operation, reducing noise to one-tenth of conventional drives
SpreadCycle™: High-dynamic current control for high-speed operation scenarios
StallGuard2™: Sensorless stall detection and protection with real-time motor load monitoring
CoolStep™: Dynamic current adaptation delivering up to 75% energy savings and reduced heat generation
Integrated 8-point motion controller: Supports point-to-point positioning, velocity control, and acceleration/deceleration curve generation without external MCU intervention
Encoder interface: Integrated ABN incremental encoder interface supporting closed-loop position feedback and lost-step compensation
Extensive I/O resources: Provides analogue inputs, digital I/O, and reference voltage source switch inputs for external sensor and limit switch integration
