Introduction
1. Product Introduction
The 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 the replacement of the complex wiring between the original mainboard and the print head with just four wires, optimizing the layout. The TOOL-LITE-232 is suitable for 36/42 stepper motors and integrates an RS232 transceiver, Type-C port, TMC2209 driver, LIS2DW accelerometer, two controllable fans, and other functions. This tool board is compatible with the Klipper firmware.
