First cable for Euler Bus power done! - AVL2016 - 06-23-2016

My little project for tonight (I forget how shaky my hands are until I start soldering..)

[Image: 2a4xnxy.jpg]

I'm using a USB-A 2.0 connector on the one end (for my Anker power brick) and a .1" pitch 3 pin receptacle on the other end, with 20 gauge wire in between.

I threw some braided cabling and heat shrink on to cover up my sins Smile

If there is any interest in a more detailed write-up and part numbers etc. just post here and I should be able to get it up sometime this weekend~

~very nice... just make sure that your 'sins' are NOT cold solder joints or possible 'short' points ! Covering them with electrical tape or shrink tubing looks good but can hide problems later when you can't figure out that mysterious powering problem. ;-)

I assume you're plugging that into euler pins (4) (6) (8) ?

No in this case my sins are of the "I didn't braid the cable as prettily as I could have" variety Wink

. I saved the cold joints for my prototype cable (not soldering in a year, I figured a little practice was good, so I bought extra parts).

I actually went with (2) (4) (6) based on this picture :

Can you please post the plugs you used?
I made one myself with a PST connector for the Euler bus but I think the connector you used is more neat.

Also, is this a 3mm sleeve?

Hi g_t_j!

The connectors are : http://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/1241152-3/A121550CT-ND/5246541

I would not use these connectors in a free-hanging application or without some sort of heat shrink stabilizing them, for free hanging applications I'd pick something from these options :

For the USB-A end I used : http://www.digikey.com/product-detail/en/assmann-wsw-components/A-USBPA/AE10091-ND/1007894

The Braiding is 1/4" : http://www.digikey.com/product-search/en?keywords=1030-1055-ND

The heat shrink I used is : http://www.digikey.com/product-search/en?keywords=q53x038b-nd

I hope this helps! Smile

Thank you very much! Great job

I'm going to try modifying some USB A to USB 4-Pin headers by moving the GND pin to connect with pin 6.

7/27: The cables arrived, then I realized that I need a way to change the gender (duh). Since I already have short USB A male to USB micro male that I like, I opted to get USB A male to USB micro female to connect the two cables together. It is difficult to find short USB A male to USB A male cables and they aren't cheap. This is definitely more expensive than making your own cables, but does save time.

8/1: I swapped the GND and USB Data+ and plugged into Euler and it worked perfectly, so all 5 boards I have are now powered via Euler with no problems.

Hello, I am very interested in feeding my pine64, you could put as working with the cable and the USB connector?.
thanks and greetings.

What does this do?
