Topic: Howto use Arduino Yun with Parallaxe BOE shield (Read 2430 times) previous topic - next topic

Hello,
I bought an Arduino Yun. Now,  I would like to plug it on my Robotics Shield Kit (for Arduino) based on    Parallax BOE Shield . Such a kit is compliant with Arduino Uno R3.

I'm a newbie in arduino so I doubt about the possibility to replace directly the uno one by the Yun one.

Have you any advice for me?

You're right, be pragmatic..

I connected my Arduino Yun to an USB cable but  I've got no power on my shied :(

First step : bad news

It seems like that shield requires 7 to 12V while the yun gives 5V

I saw this specs but why is it ok with my Uno one powered by USB too?

Hello again with my troubles with Yun and BOE Shield Parallax.

After some measuring, I realized that Yun and Uno (USB connected)  deliver the same output voltage on 5V and Vin  ~4.5 V. The respectives pins of the shield give the same thing when the switch is on 0. But when I press the switch on the shield and I pass it to one the Vin Yun down to about 2.5 V. I think that the reason why I can't powered correctly the shield.

Any idea ?

Ok I found a solution.

I just picked the 5V output of the Yun and put it in the Vin entry of the BOE Shield and now it rocks.

I suppose that I will be able to use a regulated mobile charger and to do the same sketch without a câble.
