RE: [OT] iPad query...

["Dave McLaughlin" <dave_mclaughlin@xxxxxxxxxxxxx>]

Hi Phil and all,

I have now added the 2.5mm jack to the PCB design. See here.

I have arrange it so that if you have a USB power adaptor connected and you
plug in the external power supply via the jack plug it disconnects the USB
supply to avoid them shorting out and the need for diodes.

There is a 3D PDF you can download and rotate around here. Just open with
Adobe Reader and click on the image to enable the 3D mode.

Definitely up for that - happy to paypal you some funds to contribute to
costs too of course...

Have a few USB hub PSUs flapping around - might be worth popping on a DC
jack as well (or instead) into the design so the iPad psu can be kept for
other use?
