Trinamic's StealthChop2 technology runs your steppers near-silently, while SpreadCycle delivers strong torque at higher speeds. It supports UART control — set the motor current and microstepping in firmware — plus sensorless homing via StallGuard4. With its standard StepStick footprint it drops straight into most 3D printer and CNC boards (RAMPS, SKR, MKS, Creality), making it the go-to quiet upgrade for Marlin and Klipper builds.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cul class=\"nznpd__checks\"\u003e\n\u003cli\u003eNear-silent StealthChop2 operation\u003c\/li\u003e\n\u003cli\u003eSpreadCycle mode for high-speed torque\u003c\/li\u003e\n\u003cli\u003eUART interface — set current \u0026amp; microstepping in firmware\u003c\/li\u003e\n\u003cli\u003eSensorless homing with StallGuard4 (no endstop needed)\u003c\/li\u003e\n\u003cli\u003eUp to 1\/256 microstepping with interpolation\u003c\/li\u003e\n\u003cli\u003eDrop-in replacement for A4988 \/ DRV8825\u003c\/li\u003e\n\u003cli\u003e1.4A RMS continuous, 2.0A peak per coil\u003c\/li\u003e\n\u003cli\u003ePurple PCB, standard StepStick footprint\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eSpecifications\u003c\/h3\u003e\n\u003cbr\u003e\n\u003cdiv class=\"nznpd__specs\"\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eDriver chip\u003c\/span\u003e\u003cstrong\u003eTMC2209 (Trinamic)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003ePCB colour\u003c\/span\u003e\u003cstrong\u003ePurple\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eMotor type\u003c\/span\u003e\u003cstrong\u003eBipolar stepper (2-phase, 4-wire)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eLogic voltage (VIO)\u003c\/span\u003e\u003cstrong\u003e3.3V–5V\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eMotor supply (VM)\u003c\/span\u003e\u003cstrong\u003e4.75V–29V (typ. 12V \/ 24V)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eContinuous current\u003c\/span\u003e\u003cstrong\u003e1.4A RMS per coil\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003ePeak current\u003c\/span\u003e\u003cstrong\u003e2.0A per coil\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eMicrostepping\u003c\/span\u003e\u003cstrong\u003eUp to 1\/256 (with interpolation)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eControl modes\u003c\/span\u003e\u003cstrong\u003eStep\/Dir (standalone) + UART\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eKey features\u003c\/span\u003e\u003cstrong\u003eStealthChop2, SpreadCycle, StallGuard4, CoolStep\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eFootprint\u003c\/span\u003e\u003cstrong\u003eStandard StepStick (A4988\/DRV8825 compatible)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eCooling\u003c\/span\u003e\u003cstrong\u003eHeatsink recommended above ~1A\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eWhat's in the box\u003c\/h3\u003e\n\u003cbr\u003e\n\u003cdiv class=\"nznpd__included\"\u003e\n\u003cdiv class=\"nznpd__qty\"\u003e1×\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTMC2209 stepper driver module (purple PCB)\u003c\/strong\u003e\u003cp\u003eSingle driver module with pin headers fitted.
