DC power connection to iPad Gen 1 - A1337

Hi All, I hope someone here can help, I need the ability to power up the 1st Gen iPad without the battery by using a DC PSU, I've done this with other iDevices but unable to find pinouts online for the Gen1 iPad. does anyone here know the answer to this it would be very much appreciated.

Hi Zakk,

Thanks for your response, I'm actually wanting to power on the iPad 1 without a battery, for example they make a special cable to power iPads but not the iPad Gen 1 https://www.aliexpress.com/item/Professi...

I've seen people solder wired to the power terminals of an iPhone or iPad logic board and connect a DC PSU to power it on, I know it seems extreme but its only for data recovery purposes. I was hoping to find the rails on the iPad 1 logic board that I could connect a DC power source to?

Cheers
