Introduction
1. Product Introduction
FLY TOOL-LITE-232 is a tool board designed by Guangzhou Meilun Electronic Technology Co., Ltd. for 3D printers. This tool board provides XT30/KF interfaces, allowing four wires to replace the complex wiring between the original motherboard and the print head, optimizing the layout. TOOL-LITE-232 is suitable for 36/42 stepper motors and integrates an RS232 transceiver, Type-C port, TMC2209 driver, LIS2DW acceleration sensor, two controllable fans, and other functions. This tool board is compatible with the Klipper firmware.
