Installation
Dual step motor driver shield can drive 2 step motors (4 wires 2 direction) at the same time. On dual step motor driver shield, there is a setting group for micro-step resolution. They can be set by the hardware jumper, and set by pins of Arduino or other controller. And 4 settings of micro-step resolution is at the below table:

| L | L | Full step |
| H | L | Half step |
| L | H | Quarter step |
| H | H | Eighth STEP |
