Introduction
Product Introduction
FLY SHT36 V2 is a nozzle tool board designed by Guangzhou Mellow Electronic Technology Co., Ltd. for 3D printer extruder heads. Using this tool board, you can replace the complex wiring between the mainboard and the print head with just four wires, optimizing the layout. SHT36 V2 is suitable for 36 stepper motors and integrates a CAN transceiver, USB port, TMC2209 driver, ADXL345 accelerometer, and two controllable fans among other features. This tool board is compatible with the Klipper firmware.
- Extremely compact design, utilizing a 6-layer board

- Onboard TMC2209 driver in UART mode, suitable for extruders
- Onboard ADXL345 accelerometer
- Supports PT100 (MAX31865)
- Replaceable fan MOS design
- Supports leveling sensors like BLTOUCH, PL08N, integrates XY limit switches
- Supports 12-24V voltage input
- MCU: STM32F072
- Communication: CAN
- Supports leveling sensors like BLTOUCH, PL08N, integrates XY limit switches
New Features
- Added support for switching between 4.7K resistor (for NTC thermistor) or 1.1K resistor (for PT1000)
- CAN interface no longer uses MX3.0 terminal, new connector supports 15A current, peak 30A
- Added selectable fan voltage options: 5/12/24V
