What are the specs of the DC jack? In other words, what should I google to find something that will plug into the DC jack?
dusty_nv said, “It’s 2.5mm x 5mm” but I haven’t found a DC plug with those specs. Here’s the quote:
If I google “2.5mm x 5mm DC jack” I only get results for 2.5mm x 5.5mm.
My larger goal is to hook a battery up to the Jetson so I can free it from the wall.
[s]The outer diameter of the barrel seems to be 5mm, while the inner diameter seems to be 2.5mm, just as dusty_nv said. I’ll look for a jack with those specs with more persistence. If anyone has found a way to power the dev kit with a battery, please tell me what you did.
Edit: Turns out measuring within 0.5mm is hard on a phone ruler. I think the specs of the DC plug are 2.5mm x 5.5mm. I looked up the model number of the AC adapter (GST90A19) and it has a DC plug spec of 2.5mm x 5.5mm. http://www.mouser.com/ProductDetail/Mean-Well/GST90A19-P1M/
NVIDIA has a custom GST90A19 called “GST90A19-NVDA” but I doubt they changed the DC plug specs.
Yes, the DC jack is 2DC-G213-B51, 2.5mm x 5.5mm, you can find the info here: http://www.singatron.net/online-category/2dc-g213-b51
We use an external battery bank to power our field prototypes. The RAVPower RP-PB14 comes with the correct cable and tip to plug directly into the TX-1 Dev board. It can supply 9-20VDC at ut to 4.5A and has 23000mAh capacity and will run all day and more.
