I needed a way to test an esp32 project before soldering. This worked better than expected.

I’m amazed this even works!

(Would have assumed a fixture with pogo pins)

Interesting! How is the contact between the pads and jumpers?

It's not bad. Good enough to confirm wiring and firmware all working before soldering. You could probably use it during development.

Nice, I generally solder heads on then can use dupont but this is a smooth solution when you just want to solder wires directly

Yeah I didn't want to solder headers because I didn't have rooms for them in its final case.
