MeowToast is an adapter that replaces Macintosh 3.6V logic board batteries with a CR2032 coin cell. It's here on Etsy, but sold out.
It is open source licensed and the design files are here, but this is an older version of MeowToast that uses two coin cells and some diodes. Or maybe I'm confusing MeowToast with MeowTWOast which is designed for 5V. Which Mac models need a 5V battery?
Either way, if I am getting some PCBs made on my own, I'm unclear on how this gets inserted into the battery holder. Are the edges of the PCB supposed to be copper plated? The photos on the Etsy site don't really explain it very well. This looks like the contact on the right side of the battery holder is touching the CR2032 holder, but nothing is touching on the left side. I feel like I'm missing some important detail.
