TMC2209 3D Printer StepStick Stepper Motor Driver 2.5A UART

Overview:

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:

1. Ultra quiet
2. Large heat sink,good heat dissipation
3. Support sensorless-homing function.
4. Support uart mode by set jumper caps instead of welding on mks gen_l V2.0,skr1.3/1.4,mks sgen_l.

Parameters:

Default current:0.88a
Recommend current:1.72a(at most)
Max current:2a
Logic voltage:3.3v/5v
Input voltage:5.5v-28v
Microstep:up to 1/256
 
Driver current regulation:

1. Verf measures the voltage of Gnd and potentiometer middle.
2. Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive.
3. Please connect the power supply when measuring voltage as well, do not connect only the USB power.
4. Please pay special attention to the direction, do not insert wrongly!

Notice:

1. Pay attention to the connection direction,do not reverse it.
2. 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.
3. Dir/step mode used in the printer control board, please pay attention to set the jumper cap MS1 MS2.
