Bigtreetech TMC2209 V1.3 Stepper Motor Driver

TMC2209 V1.3 VS TMC2208, more of these functions: 1. Blocking rotation detection Stallguard--TMC2209 provides a load and loss of speed detection technology 2. Current dynamic adjustment Coolstep--TMC2209 provides a current dynamic regulation technology that saves up to 75% of electrical energy. - stealthChop2 - for quiet operation and smooth motion - spreadCycle - highly dynamic motor control chopper - coolStep - current control for energy savings - stallGuard4 - sensorless motor load detection The hardware of the modes UART,DIR/STEP is the same. If you need to use UART mode, just need to modify the firmware.
