Introduction

Product Overview

FLY-SHT36-PRO is a hotend tool board designed by Guangzhou Meilun Electronic Technology Co., Ltd. for 3D printer extruders. With this tool board, four wires can replace the complicated wiring between the main board and the print head, optimizing the layout. FLY-SHT36-PRO is suitable for 36 stepper motors and integrates a CAN transceiver, USB port, TMC5160 driver, ADXL345 accelerometer, two controllable fans, and other functions.

• Extreme size reduction, designed with a 6-layer board
• Supports CAN bus connection, more stable data transmission, lower latency, and more reliable connection
• Onboard TMC5160 for extruder
• Onboard ADXL345 accelerometer
• Supports PT100 (MAX31865)
• Replaceable fan MOS design
• Supports BLTOUCH, PL08N, and other leveling sensors, integrates XY limit switches
