Product Introduction

FLY-SHT36-LIS3DH is a hotend tool board designed by Guangzhou Meilun Electronic Technology Co., Ltd. for 3D printer extruders. Using this tool board, four wires can replace the complex wiring between the original mainboard and the print head, optimizing the layout. FLY-SHT36-LIS3DH is suitable for 36 stepper motors and integrates a CAN transceiver, USB port, TMC2209 driver, LIS3DH accelerometer, two controllable fans, and other functions. This tool board is compatible with the Klipper firmware.

  • Extremely compact size, designed with a 6-layer PCB
  • Supports CAN bus connection for more stable data transmission, lower latency, and more reliable connections
  • Onboard TMC2209 driver, operating in UART mode, suitable for extruders
  • Onboard LIS3DH accelerometer
  • Supports PT100 (MAX31865)
  • Replaceable fan MOSFET design
  • Supports leveling sensors such as BLTOUCH and PL08N, with integrated XY limit switches
  • Supports 12-24V voltage input
  • MCU: rp2040
  • Communication: CANBUS
