Introduction
1. Product Overview
FLY TOOL-LITE-232 is a tool board designed by Guangzhou Meilun Electronics Technology Co., Ltd. for 3D printers. This tool board provides xt30/kf interfaces and uses four wires to replace the complicated wiring between the main board and the print head, optimizing layout. TOOL-LITE-232 is suitable for 36/42 stepper motors, and it integrates an RS232 transceiver, TypeC port, TMC2209 driver, LIS2DW accelerometer, two controllable fans, and other features. This tool board is compatible with Klipper firmware.
