Shield + UNO R3 Board + 4 X A4988 Driver Kit For Arduino 3D Printer Red

Descriptions:

1. Arduino Shield V3 3D Printer Expansion Board

This expansion board as a driver expansion board, can be used for machines, 3D printers.
It is a total of four slots, can drive four A4988 motor.
Each road motors need two IO ports. In words, six IO ports can be well managed three motors. Very convenient to use.
UNO for Arduino module IO port correspondence introduction.

2. A4988 Reprap Step motor driver module

Simple step and direction control interface
Short-to-ground and shorted-load protection
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your motor’s rated voltage to achieve higher step rates

3. UNO R3 Development Board

Package Included:
1 x Shield V3 Expansion Board
4 x A4988 Step Motor Driver Module
4 x Heatsink
1 x UNO R3 Board
