- 【Silent Motor Operation】The TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors.Voltage output capacity ranges from 5V to 28 V. It can operate bipolar stepper motors from 1 to 1/256 step modes. TMC2209 uses StealthChop2 technology for silent motor operation.
- 【Sensorless Homing】The TMC2209 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.
- 【Dynamic Current Control】The CoolStep technology allows the TMC2209 to control the current dynamically, reducing the heat generation of the stepper, which in turn diminishes the need for cooling.
- 【Supports UART, STEP/DIR Modes】BIGTREETECH 4PCS TMC2209 V1.2 UART stepper motors support UART, STEP/ DIR Mode, except that you need to modify the firmware for the mode you use.
