Introduction

Product Introduction

The FLY SB2040 PRO is a tool board developed by Guangzhou Magnesium Electronics Technology Co., Ltd. for the VORON Stealthburner print head. Using this tool board, four wires can replace the complex wiring between the original motherboard and the print head, optimizing the layout. The SB2040 is suitable for stealthburner and afterburner. It integrates a CAN transceiver, USB port, TMC2240 driver, ADXL345 accelerometer sensor, three controllable fans, and other functions. This tool board is compatible with Klipper and RRF firmware.
