Introduction
1. Product Overview
FLY TOOL-LITE-CAN is a tool board designed by Guangzhou Meilun Electronics Technology Co., Ltd. for 3D printers. This tool board provides XT30/KF connectors, enabling four wires to replace the complicated wiring between the mainboard and print head, optimizing layout. TOOL-LITE-CAN is suitable for 36/42 stepper motors. It integrates a CANBus transceiver, Type-C port, TMC2209 driver, LIS2DW accelerometer, two controllable fans, and other features. This tool board is compatible with Klipper firmware.
