Mellow Fly-SHT36 PRO V1 Board With 1M Can Cable for Klipper with PT100

The FLY-SHT36-PRO is a headtool board designed by the FLY team specifically for 3D printer extruder heads. With this tool board, you can replace the complex wiring between the main board and the print head with just four wires, optimizing the layout. The FLY-SHT36-PRO is suitable for 36-step motors and integrates a CAN transceiver, USB port, TMC5160 driver, ADXL345 accelerometer, two controllable fans, and other functional tool boards. This tool board is compatible with Klipper firmware.

Higher Current Capacity: The TMC5160 can handle a higher current than the TMC2209. This means it can drive larger, more powerful motors. This can be particularly useful in 3D printers that are designed to handle larger print volumes or higher-speed operations.

Advanced Features: The TMC5160 comes with more advanced features, such as a larger microstepping interpolator for smoother and quieter operation. It also has an integrated motion controller that can offload computation from the main processor.

Higher Precision: The TMC5160 offers higher precision and accuracy compared to the TMC2209, which can result in better print quality.
