Mellow SHT36 V3 Canbus Board
The FLY-SHT36 V3 is a tool board specifically designed by the FLY team for 3D printer extruder heads. With this tool board, you can replace the complex wiring between the mainboard and the print head with just four wires, optimizing the layout. The FLY-SHT36 V3 is suitable for 36-step motors and integrates a CAN & RSR232 transceiver, USB port, TMC2209 driver, LIS2DW accelerometer, two controllable fans, and other functionalities. This tool board is compatible with Klipper firmware, and the Max version can be used with both RRF & Klipper, supporting Eddy LDC1612.
The SHT36 V3 board utilizes CAN/RS232 communication to connect the upper computer to the UTOC/UTOR board, enabling communication with the SHT36 through the UTOC/UTOR
