From the project

Adapter PCB and Kicad Library to make adding component-less program and debug footprints to your PCBs as easy as possible

My blog post about this project Look ma, I was featured on Hackaday!

One of the things I've noticed in a lot of beginner ESP32 PCBs is a lack of hardware debugging interfaces, which is understandable since setting up JTAG can be a bit confusing when you're first exposed to it. This project's goal is to make using JTAG and connector-less footprints on your PCBs as easy and cheap as possible.
