There are a few places you can tap into the 3V3 rail, including pins 14/15 on the card edge, any vias attached to those pins, or pin 28 on the chip, or just use a continuity tester and use anywhere on the board connected to the rail. It's been awhile since I've done anything with these, so I can't 100% confirm that will do it, but it should. If you want to be safe, you could use a 10K resistor instead of just connecting it directly (i.e. BAT+--10K--3V3).qwertymodohttps://www.blogger.com/profile/17335329668705867365noreply@blogger.comtag:blogger.com,1999:blog-2953283389087359631.post-90629752933557962902017-05-09T02:02:02.667-07:002017-05-09T02:02:02.667-07:00I've swapped my sram for an fram ramtron chip....I've swapped my sram for an fram ramtron chip. Could you please explain what else you need to do other than swap out the sram and remove battery? You mentioned a resistor...Anonymoushttps://www.blogger.com/profile/04808790161252074524noreply@blogger.com
