Introduction

1. Product Introduction

FLY TOOL-LITE-CAN is a tool board designed for 3D printers by Guangzhou Mullen Electronic Technology Co., Ltd. This tool board provides xt30/kf interfaces, which can replace the complicated wiring between the mainboard and the print head with four wires, optimizing the layout. TOOL-LITE-CAN is suitable for 36/42 stepper motors, and it integrates CANBus transceiver, TypeC port, TMC2209 driver, LIS2DW accelerometer sensor, two controllable fans and other functions. This tool board is suitable for Klipper firmware.
