Another AT2XT
ORIGINAL GITHUB: https://github.com/hkzlab/Another_AT2XT
This is nothing more than another PCB for the AT2XT project you can find HERE.
I needed something slightly smaller than what provided for the original project, and that did not need as many connector cables. So I've designed this to cater to my needs.
Disclaimer
I take NO responsibility for what happens if you decide to build and use this card. Your computer might crash, catch fire or be destroyed in other nasty ways. You're encourauged to take what you deem fit from this, and use it in your projects!
