Power Supply for Intel Edison Arduino Board

Jump to solution

Hi,

Looking at this page:

https://software.intel.com/en-us/get-started-edison-linux https://software.intel.com/en-us/get-started-edison-linux

These are the requirements:

7-15V DC

At least 1500mA

The center/inner pin should be the positive pole of the power supply

But it doesn't clarify the size of the 5.5mm barrel connector (see below).

And this is the suggested part number: EMSA120150

According to DigiKey it is a non-stock item BUT has a direct substitute of SMI18-12-V-P5:

http://www.digikey.com/product-detail/en/EMSA120150K-P5P-SZ/T1109-P5P-ND/2352102 http://www.digikey.com/product-detail/en/EMSA120150K-P5P-SZ/T1109-P5P-ND/2352102

Looking at the datasheet for the smi18:

http://www.cui.com/product/resource/smi18.pdf http://www.cui.com/product/resource/smi18.pdf

Scrolling down to page 4, there are TWO 5.5mm choices.

5 & 6 both have an outside diameter of 5.5mm. 5's inside diameter is 2.1mm and 6's is 2.5

Question: Does the Edison Arduino board require the the 2.1mm which is size 5 and therefore matches the SMI18-12-V-P5.

Regards,

Bill

Hello Bill.,

If you check the datasheet of the recommended power supply, you will find that it has a 2.1mm I.D. Also, I realized that the item is in stock so I recommend you to check again. Anyhow, if you want to get another power supply, the I.D must be 2.1mm.

Regards,

Diego.
