BIGTREETECH DIRECT 5PCS TMC2209 V1.2 Stepstick UART Stepper Motor DriverNote:*Item is new. May be missing 4 heatsinks*
Product Features
【Silent Motor Movement】Thanks to StealthChop2 technology, TMC2209 allows for silent motor operation. The TMC2209 drivers work with a continuous current up to 2.0A, peaks of 2.8A.
【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, allowing higher current intensities and better thermal performance, which saves up to 75% of electrical energy.
【Supports UART, STEP/DIR Modes】BIGTREETECH 5PCS TMC2209 V1.2 UART stepper motors support UART, STEP/ DIR Mode, except that you need to modify the firmware for the mode you use.
Product Details

StallGuard4 - sensorless motor load detection
What is the difference between TMC2208 and TMC2209 SilentStepSticks?
TMC2209 SilentStepSticks have output drivers with a lower power dissipation and a higher current is possible.
TMC2209 SilentStepSticks feature coolStep and stallGuard4(optimized for stealthChop).
TMC2209 SilentStepSticks can be switched between stealthChop and spreadCycle mode via a configuration pin(SPREAD).
TMC2209 SilentStepSticks drivers have the v2 pinout(Vref and DIAGO swapped).
TMC2209 V1.2 VS TMC2208, more of these functions:
Blocking rotation detection
Stallguard--TMC2209 provides a load and loss of speed detection technology
Current dynamic adjustment
Coolstep--TMC2209 provides a current dynamic regulation technology that saves up to 75% of electrical energy.
