This V4.1B bord can only be a replacement for V4.1B board, can not replace V4.0 board or other board .
pls check which board does your printer has before order . the board type will be written on the board itself .
need order a same board as your priter originally has. otherwise will not be compatible .
A4988 stepper drivers are soldered on this board.
Here are its main features:
1. Using ATMEGA2560 as its core chip, with its flash memory at 256KB and operating frequency at 16MHz.
2. Compatible with 12V/24V input voltage. Featuring dual power supply, one for powering up the heatbed (15A), the other for other electronic parts (10A).
3. The interface for the heatbed comes with a high-power MOS tube, which is of ultra-low conductive internal resistance. High performance and stable.
4. With 2 interfaces for normally open fans and 1 interface for LED light.
5. Driven by 6 A4988 stepper motors for a single extruder or multiples ones.
6. With extension interfaces for LCD display and SD card. Support both 2004 and 12864 LCD display.
