Arduino CNC shield v3 engraving machine expansion board 3D printer A4988 driver board

This expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There are a total of 4 slots for stepper motor drive modules. Can drive 4 stepping motors, and each stepping motor only needs 2 IO ports, that is to say, 6 IO ports can manage 3 stepping motors very well, it is very convenient to use, farewell The operation of traditional stepping motors is cumbersome.

UNO R3 development board MCU mega328p / 2560 chip Ardu expert improved version ch340

Uno R3 is an easy-to-use open-source controller. Compared with uno, there is no big change in hardware. The biggest difference is that the USB to serial port circuit is replaced by an atmega16u2 single-chip microcomputer, so the cost is also increased. The software part is the same as before, and there is no big change.
