Description

Features:

This expansion board can be used as a driver expansion board for engraving, 3D printers.

Total of 4 slots can drive 4 A4988 stepping motors. Each road stepper motor requires two IO ports. In other words, 6 IO ports successfully manage 3 stepping motors. Very convenient to use.

UNO of the introduction of Arduino modules with IO ports.

Note: When inserting A4988 module, please be careful not to insert the other side. Stepping motor wiring is as follows:

Figure 2A, Figure 2B, is a group (red, green), and Figure 1A, 1B, is a group (blue, yellow). If you want to change the direction, you can change the position of one group. For example, 2A, 2B will be interchanged.
