This is a minimalistic adapter thing to flash those sp111 with little effort.

I mean yes I had to soldered a bit at the pogo pins but this was much simpler than trying to get the PCB out or solder in the housing.

An advantage here is that you can see if the pogo pins are on the pads and you can adjust them. It is designed for D 1,37 mm pins so with my printers tolerances they still have some wiggle room to be adjusted.

But you have to hold and press it for like 1 min while ESPEasy-Flasher flashes.
