Hi, nottheoilrig,
Nice find, Pogo’s on Amazon, I 3d printed the adapter and added the right angle Pin headers for pins and connections. I’ll 3D Print one like the Xiao/QT and allow holes where battery connection for pogo’s for a complete solution, the socket is in the link on my post about btw, AFAIK you can only use the pads to take advantage of the battery charging capability. You can direct connect to pins like 3,3 and NOT use the USB connector at the same time obviously.
