Olimex EMG Shield and Arduino Leonardo

[devnull]

Dear Olimex gang,

Quick question, just wanted to confirm that before the purchase - are Olimex EMG Shield and Arduino Leonardo  compatible? It seems to me that pin layout is the same but what about voltage and other aspects?

Apologies if this is too obvious, I'm complete beginner in this world.

Much appreciate your help.

Hey devnull,

The library for Arduino IDE should work with all the original Arduino boards and Olimex Arduino boards. I mean this one: https://www.olimex.com/Products/Duino/Shields/SHIELD-EKG-EMG/resources/ShieldEkgEmgDemo.zip.

Do not hesitate to ask further questions.

Best regards,

Thanks for getting back to me.

Yeah, I have tested Arduino Leonardo board with EMG shield and it seems to work indeed.
While I'm here, what are your recommended settings for shield voltage jumper? Should it be set on 3.3v or 5v?
Could you briefly clarify in what situations it makes a difference?

Cheers

Good question, I would like to know the same thing for Arduino Due
Thanks

Hello ellecieffe,

It makes no difference for the function of the shield. It is there to be compatible both with main boards that provide 3.3V and main boards that provide 5V to the shield mounted.

Arduino Due, for example, provides 3.3V.
