BIGTREETECH SKR V1.3 Control Board 32Bit Smoothieboard+TMC2209 V1.2 UART+TFT35 V2.0 3D Printer Part
[33030912565] Kit and TMC2209 V1.2: 1PC * SKR V1.3 32 Bit Board 1PC * TFT35 V2.0 5PC * TMC2209 V1.2 Driver 1Set * Wire Kit and TMC2208 UART: 5PC * TMC2208 V3.0 UART Driver TMC2209 Features: Stepper Motor Driver based on a Trinamic TMC2209 - Hardware compatible with StepStick and Pololu A4988 - Step/Dir interface with microstep interpolation (up to 256 microsteps) - Drive capability up to 2.0A (RMS) continuous coil current - 2.8A Peak - Configuration via CFG pins or UART interface - Motor voltage: 5.5-28V - Logic voltage: 3.3-5V - RSense: 0.11 Ohm - 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 three modes of UART,DIR/STEP is the same. If you need to use UART mode, just need to modify the firmware. BIGTREETECH TMC2209 V1.2 UART firmware : https://github.com/MarlinFirmware/Marlin/pull/14215?fbclid=IwAR1QJDcuRzzhg7TihQcsfGTyx4UPcmtfhqhRw0gCzRL5gfqj5ZMC36wpN5M TMC2209 V1.2 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.
