MKS TMC2209 2209 Stepper Motor Driver

MKS TMC2209 2209 Stepper Motor Driver StepStick 3d printer parts 2.5A UART ultra silent For SGen_L Gen_L Robin Nano Tmc2209 have all function of tmc2208,can completely replace tmc2208. At the same time,tmc2209 have better heat dissipation,support bigger current,support sensorless-homing function. Features: Ultra quiet Large heat sink,good heat dissipation Support sensorless-homing function. Support uart mode by set jumper caps instead of welding on mks gen_l V2.0,skr1.3/1.4,mks sgen_l. Parameter: Default current:1.25a Max current:2.5a Logic voltage:3.3v/5v Input voltage:5.5v-28v Microstep:up to 1/256 Mode:dir/step,uart Microstep set: Microstep setting M0 M1 STEP GND GND 8 VCC_IO GND 32 GND VCC_IO 64 VCC_IO VCC_IO 16 Driver current regulation: Verf measures the voltage of Gnd and potentiometer middle. Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive. Please connect the power supply when measuring voltage as well, do not connect only the USB power. Please pay special attention to the direction, do not insert wrongly! Driver current algorithm: I=Vref Default I=1.25A Notice: Pay attention to the connection direction,do not reverse it. The motor direction is opposite to that of A4988 and DRV8825, please adjust the firmware or adjust the motor wiring if you want to change A4988. Dir/step mode used in the printer control board, please pay attention to set the jumper cap MS1 MS2
