Note: TMC2209 V1.3–This new version does not carry the wire, which will not affect usage.
TMC2209 V1.3 VS TMC2208, more of these functions:
1. Blocking rotation detection
Stallguard–TMC2209 provides a load and loss of speed detection technology
2. Current dynamic adjustment
Coolstep–TMC2209 provides a current dynamic regulation technology that saves up to 75% of electrical energy.
– stealthChop2 – for quiet operation and smooth motion
– spreadCycle – highly dynamic motor control chopper
– coolStep – current control for energy savings
– stallGuard4 – sensorless motor load detection
The hardware of the modes UART,DIR/STEP is the same. If you need to use UART mode, just need to modify the firmware.

Avoid losing steps and Jittering, Good heat dissipation
Immersion Gold process, Ultra-quietSpecificationDimensionsComparison
Good heat dissipation
Large heat dissipation area, good heat dissipation effectUltra-quiet
StealthChop can driver the motor towork under extreme silenceAvoid losing steps and jittering
SpreadCycle: The motor controlled by the PWM choppermode operated more smoothly and without JitterIt can effectively avoid problem such as running deviation losing step and fault caused by the overlode of the chipImmersion Gold process

As shown in the figure to the right,if the 5th Pin is used as the UART Pinthe resistance shall be removed and welded to the following two pads.Potentiometer adjustment instructions
1. Rotate the potentiometer clockwise: reduce Vref to reducethe driver current
2. Turn the potentiometer counterclockwise: Increase Vref toincrease the driver currentNote:
1.When the driver is inserted into the motherboard, pleasepay attention to see the direction of the drive, can notbe inserted in reverse, to prevent the drive from burning
2.Be sure to do a good job before driving heat dissipationwork (heat sink + fan), to prevent the drive is notworking properlyProduct DetailsWhat’s in the box?
