BIGTREETECH TMC2209 V1.3 Stepper Motor Driver
BIGTREETECH TMC2209 V1.3
Avoid losing steps and shaking, the gold immersion process has good heat dissipation and is super quiet.

Working mode: STEP/DIRECT, UART

_UART mode, already soldered.
As shown in the figure on the right, if Pin 5 is used as a UART Pin, the resistor will be removed and soldered to the following two pads.

_UART mode of TMC2209 V3.0 connection to motherboard

Potentiometer adjustment instructions
1. Turn the potentiometer clockwise: decrease Vref to decrease the control current
2. Turn the potentiometer counterclockwise: Increase Vref to increase the control current.

1. When installing the driver into the motherboard, pay attention to the direction of the drive, it cannot be inserted backwards, to avoid the drive being burned.
2. Make sure to do a good job of heat dissipation (heat sink + fan) before operating, to avoid the inverter from operating abnormally.
