They say the 5V ⎓ 3A power supply needs to be connected through the Orange Pi One’s DC socket. However, they don’t mention the size of barrel connector¹ (outer diameter & inner diameter) that will actually fit inside the DC socket.
Does anyone here know?

- comboy 10y agoI don't have it at hand to measure but it's not something typical. I suggest getting an offer on aliexpress where they include dc barrel to usb cable. edit: outer diameter 4mm
- arm 10y agoThanks for the firsthand confirmation; I appreciate it!
- makomk 10y ago4.0mm/1.7mm barrel plug, centre positive according to http://linux-sunxi.org/Xunlong_Orange_Pi_Plus http://linux-sunxi.org/Xunlong_Orange_Pi_Plus - I think it's the same on all of the Orange Pi boards.
- arm 10y agoOh, nice, thanks for that link and info! As you mentioned, the page even lists the output plug polarity¹ it requires (centre positive)! EDIT: Just realized that’s the same size barrel connector used for Sony’s PlayStation Portable², PlayStation TV³, etc., and the power supply⁴ those devices come with is 5V ⎓ 2A and have a centre positive polarity, so it seems like they’ll be perfect for use on the Orange Pi One. ―――――― ¹ — https://en.wikipedia.org/wiki/Polarity_symbols https://en.wikipedia.org/wiki/Polarity_symbols ² — https://en.wikipedia.org/wiki/PlayStation_Portable https://en.wikipedia.org/wiki/PlayStation_Portable ³ — https://en.wikipedia.org/wiki/PlayStation_TV https://en.wikipedia.org/wiki/PlayStation_TV ⁴ — http://f.cl.ly/items/3I3N1m0U1E3o3I1q0v19/sony_ps_tv_ac_adaptor.JPG http://f.cl.ly/items/3I3N1m0U1E3o3I1q0v19/sony_ps_tv_ac_adap...
- wyldfire 10y agoDon't DC power jacks come keyed for at least voltage/polarity? If not -- why‽
- khedoros 10y agoThey come in various shapes, varying on inner diameter, outer diameter, and length. Smaller connectors may tend to be lower voltage, but that's certainly always true. There are several standards, and at least some of them specify voltage ranges for particular sizes, but there's no universal standard.

- toomanybeersies 10y agoCould always solder on a mini/micro usb header for power. Just pick up 10 from aliexpress while getting your Orange Pi.
