HELP Connected 4 motors to EDISON Board

[RBart4]

Hello everybody,

I would like to connect 4 motors to my Intel Edison board, there are 3V and 70mA DC motors. They will be activated in same time, so I planned to use a command signal (from an other board), but I don't know what kind of shield I need. I saw the GPIO intel board http://www.amazon.com/gp/product/B00VY9ZBE6?keywords=GPIO%20Edison&qid=1445458412&ref_=sr_1_2&sr=8-2

but is it enought to activate my 4 motors (I will use a 3,7V 400mAh battery) ? Should I use an H-Bridge (I don't need to change the rotary) ? If yes, I saw a sparkfun kit for the EDISON board, but where could I connect my command signal ?

Thank you for your help !

Hi Memphis27,

You can use the Edison Module with the mini breakout board for this. If you want to use 4 pins for PWM you can, the module has 4 pins for this:

J18 - pin 7 : GP12_PWM0

J18 - pin 1 : GP13_PWM1

J17 - pin 1 : GP182_PWM2

J18 - pin 8 : GP183_PWM3

I suggest you to use a shield with drivers for the motors; with this you will be able to manage the current and voltage in the motors. Take a look at the http://download.intel.com/support/Galileo-Edison_ShieldTestReport_330937-002.pdf Shield Testing Report, you will find some examples with motors that may help you with this.

Also, take a look at the Hardware Guides of the module and breakout board.
