Features 1、GOOD PERFORMANCE: The stepper motor driver board is ultra quiet, with high current, 256 microstep subdivision, and good heat dissipation effect. 2、UART MODE SUPPORT: The stepper motor driver supports UART mode and is used in conjunction with MKS SGEN‑L without the need for jumpers. 3、REPLACEMENT PART: TMC2209 has all the functions of TMC2208 and can completely replace TMC2208, supporting sensorless feedback function. 4、HIGH CURRENT: With the characteristic of low heat generation, supports higher current, a maximum peak current of 2.5A and infinite return to zero. 5、EASY OPERATION: Supporting the Uart module by wearing a jumper cap instead of soldering it onto the mks, with easy operation and good stability.
