For StepStick and Pololu A4988 compatible hardware. Drive capability up to 1.7A continuous coil current, up to 2.8A peak. Step/Dir interface with microstep interpolation (up to 256 microsteps). Configurable via CFG pins or UART interface. stealthChop2 for quiet operation and smooth motion. Extended high dynamic motor control chopper available through UART, OTP, or CFG pins. coolStep current control for energy efficiency. StallGuard4 sensorless motor load detection. TMC2209 is an ultra-quiet motor driver IC for two-phase stepper motors. Pin compatible with many traditional drivers and TMC2208. Advanced StealthChop2 technology ensures noise-free motor operation with high efficiency and torque. Fast current regulation and resonance suppression enable high dynamic performance. StallGuard allows sensorless homing and stall prevention. Built-in power MOSFET handles motor currents up to 2A, with protection and diagnostic features for stable operation. UART interface enables tuning and control options. Application settings can be stored in OTP memory. Supports silent and precise operation via pulse direction control, offering a cost-effective and competitive solution. Color: Blue + White. Material: Plastic. Size: 2.01 x 1.51 cm.
