BIGTREETECH TMC2209 Stepper Motor Driver

【Dynamic Current Control】The CoolStep technology allows the TMC2209 to control the current dynamically, allowing higher current intensities and better thermal performance, which saves up to 75% of electrical energy.
【Supports UART, STEP/DIR Modes】BIGTREETECH 4PCS TMC2209 V1.2 UART stepper motors support UART, STEP/ DIR Mode, except that you need to modify the firmware for the mode you use.
