Toaiot 3D Printer Stepstick Mute TMC2209 V4.0 Stepper Motor Driver UART Mode with Heatsink for Reprap1.4 MKS Gen/SKR V1.3 Ramps GEN L1.4/1.5/1.6 Control Board 5Pcs

TMC2209 V4.0: ultra-silent motor driver, 2022 New Version, compatible to a number of legacy drivers as well as to the TMC2208, Support UART mode, compatible with popular motherboards such as FYSETC S6/F6, SpideKing, MKS SGENL, MKS GENL v2.0, MKS RobinE3D, SKRv1.3/1.4. Heat sink color is random: Blue or Black. Upgrade Tips: add CLK pin, not connect in default, tie to GND via 0R; SPREAD pin is floating. Reserve pull-up and pull-down resistors. Move TX from 3 to 5. Advantage 1: StallGuard for sensorless homing. The integrated power MOSFETs handle motor currents up to 2A RMS with protection and diagnostic features for robust and reliable operation. A simple to use UART interface opens up tuning and control options. Store application tuning to OTP memory. Advantage 2: Industries’ most advanced STEP/DIR stepper motor driver family upgrades designs to noiseless and most precise operation for cost-effective and highly competitive solutions. Advantage 3: Step/Dir Drivers for Two-Phase Bipolar Stepper Motors up to 2.8A peak –StealthChop for Quiet Movement – UART Interface Option –Sensorless Stall Detection StallGuard4.
