The TMC2209 is an ultra-quiet two-phase stepper motor driver chip with a continuous drive current of 2A and a peak current of 2.8A.
Compared to the TMC2208, the drive current is improved by 0.6A--0.8A, while the Blockage increases the stall detection function.
Provides up to 256 segments;stallguard4TM stall detection, which can feed back an abnormal signal when the motor rotates abnormally.

Note:
Always disconnect the power supply before installing the drive to prevent the drive from burning.
Be sure to confirm the direction of the drive before installing the drive to prevent the drive from being burnt due to reverse connection.
Do not plug or unplug the drive module with power to avoid damage.
When installing the heat sink, pay attention to the contact between the heat sink and the pin header.Stop drive short circuit.
The product is sensitive to static electricity, please handle it carefully when using, it is best to move it again when using.
Must be used to heat the drive before use (heat sink, cooling fan).

Package Included:
4 X TMC2209 V1.2 stepper motor driver
4 X Jumper cable
