Ultra-silent Stepper Motor driverBIGTREETECH TMC2209 V1.3 stepper motor driver adopts StealthChop2 silent motor operation technology is an ultra-silent motor driver IC for two-phase stepper motors. Continuous current up to 2.0A (peak 2.8A),voltage ranges from 5.5V to the maximun output of 28V.It can operate bipolar stepper motors from 1 to 1/256 step modes. Supports UART, STEP/DIR ModesBTT TMC2209 stepper motor driver support UART, STEP/ DIR Mode, except that you need to modify the firmware for the mode you use. for detailed tutorials, please refer to the BIGTREETECH GITHUB instructions. Sensorless HomingThe BTT TMC2209 v1.3 stepper motor driver incorporated StallGuard technology to detect alterations in the motor current and use this measurement to detect the end of an axis' stroke and produce 3D printers without limit switches. More cost-effective The TMC 2209 stepper driver is compatible with all FDM 3D printer on the market, eliminating the
