BIGTREETECH TMC2209 V1.2 UART Stepper Motor Driver Accessory for 3D Printer Two-Phase Stepper Motors

BIGTREETECH TMC2209 V1.2 UART Stepper Motor Driver Accessory for 3D Printer Two-Phase Stepper Motors

Description:
TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. Its continuous drive current is 2A and peak current is 2.8A. Compared with TMC2208, the driving current of this IC is not only improved by 0.6A-0.8A, but also this IC increases the function of locked-motor test.

Flexible microPlyer interpolation unit can provide 256 micro-steps. Stallguard4™locked-motor test can provide an abnormal signal when the motor rotates abnormally. CoolStep™ current dynamic control can save 75% energy. The sinusoidal control can be perfectly realized even in the system with limited pulse frequency. Since stealthChop2 ™ ultra-quiet technology is widely used in 3D printing, the design of these components is also compatible with existing 3D printer electronic devices, and it eliminates the expensive cost of redesigning.The module has a standard step/dir interface, it's easy to use.

Features:
- The motor is difficult to lose steps
- Ultra-quiet mode
- The module has a large-area cooling pad and it can lower the temperature when drive is working
- The module can prevent the motor from shaking
- The module supports locked-motor test
- The module supports STEP/DIR and UART mode

Package Included:
- 1 x TMC2209 V1.2 Stepper Motor Driver

1. Vref range: 0.2V-2.2V
2. Default Vref: 1.2V±0.1V
3. Default current: 0.9A
4. Potentiometer regulation: Rotate the potentiometer clockwise to reduce the Vref voltage and the drive current can be reduced. Rotate the potentiometer counterclockwise to increase the Vref voltage and the drive current can be increased.

Precautions:
1. Be sure to disconnect the power supply before installing the driver to prevent the drive from burning.
2. Before installing the driver, be sure to confirm the direction of the drive to prevent the drive from burning due to reverse connection.
3. Pay attention to the line sequence and IO port when wiring. Connecting the wrong line will directly cause the drive to not work. Carefully connected, corresponding to the above illustration.
4. Do not plug and unplug the drive module with power to avoid damage.
5. When installing the heat sink, there can be no contact between the heat sink and the pin header pin to prevent short circuit of the drive.
6. The product is sensitive to static electricity, please handle it carefully when using. It is best to remove the packaging when using.
7. Before use, be sure to do heat dissipation treatment of the driver (heat sink, cooling fan, etc.).
