Introduction

Product Introduction

The FLY-SHT36-PRO is a toolboard designed by Guangzhou Melyun Electronic Technology Co., Ltd. for the print head of 3D printers. Using this toolboard, four wires can replace the complex wiring between the original motherboard and the print head, optimizing the layout. The FLY-SHT36-PRO is suitable for 36 stepper motors and integrates a CAN transceiver, USB port, TMC5160 driver, ADXL345 acceleration sensor, two controllable fans, and other functional toolboard features.

• Compact size to the extreme, designed with a 6-layer PCB
• Supports CAN bus connection for more stable data transmission, lower latency, and more reliable connection
• Onboard TMC5160 for extruder use
• Onboard ADXL345 acceleration sensor
• Supports PT100 (MAX31865)
• Replaceable fan MOSFET design
• Supports leveling sensors such as BLTOUCH and PL08N, integrates XY limit switches
• Supports 12-24V voltage input
• MCU: Raspberry Pi RP2040, Dual core ARM Cortex-M0+@133MHz
• Communication: CANBUS, USB
