hello, I want to know the voltage that provide two channels for motor DC

Hello,

one shield with one stepper is nice for one direction.
Is it possible to connect a second Motor Shield R3 at the Arduino?

Thanks for information

yes you can use two, but not one on the other, you must put the other one next to your Arduino connect the pins of the "side-car" shield to others pins than the ones used by the first one ex:

==============================================
Arduino pin| shield on the Arduino | side-car shield
=========|===================|================
0              |NC                          |NC
1              |NC                          |NC
2              |NC                          |BRAKE A
3              | PWM A                    |NC
4              |NC                          |BRAKE B
5              |NC                          |PWM A
6              |NC                          |PWM B
7              |NC                          |DIR A
8              |BRAKE B                   |NC
9              |BRAKE A                  |NC
10            |NC                          |DIR B
11            |PWM B                     |NC
12            |DIR A                       |NC
13            |DIR B                       |NC
A1            |SNS 0                      |NC
A2            |SNS 1                      |NC
A3            |NC                         |SNS 0
A4            |NC                         |SNS 1
A5            |NC                         |NC
======================================
(you can change the pins connection of the side car shield if you want but make sure that you don't use a used pin by the "on Arduino" shield.
Of course you also need to connect the Vin pin, Gnd pin and 5V pin.

I don't have two shield so I can't show you a photo but it is something easy to do.
