A4988 arduino cnc shield engraving machine 3d printer expansion board
Description:
This expansion board as a driver expansion board v3, can be used for engraving machines, 3d printingers
It is a total of four slots, can drive four a4988 stepper motor. Each road stepper motors only need two io ports. In other words, six io ports can be well managed three stepper motors
Io corresponding figure above

Consider:
When entering module a4988, be careful not to enter the opposite.
Cable motors as follows: 2a, 2b is a group (red, green), 1a, 1b is a group (blue, yellow),
If you want to change direction, you can change the position of one group, for example 2a, 2b exchanges.
