Dual stepper motor driver shield can drive 2 stepper motors at the same time by Arduino. It can work with the power supply from 4.75V to 30V. High accuracy controlling can be supported by Arduino for CNC milling machine.
The D1 is an Arduino Uno-like wifi board based on ESP-8266EX.
11 digital input/output pins
1 analog input(3.3V max input)
a Micro USB connection
a power jack, 9-24V power input.
Compatible with Arduino
This is a splittable 40 pin jumper wire, it is super flexible, can be transformed from 1-40 pin jumper wire. With some of these, you will no need to worry about the jumper wires you got before do not fit your project, just split it and go.
The Screw Shield extends all pins of the Arduino out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield, including: a large prototyping space of both connected and unconnected 0.1" spaced through-holes, a couple 5V and GND busses, a reset button, and a 5mm green LED.
