Custom board that re-uses a D1 Mini's carrier board to serve as a USB->Serial->ESP programming jig.

Designed the PCB in Eagle CAD, produced at OshPark.

1) Desolder the ESP module off of the D1 Mini board(using hot air).
2) Solder Pogo pins to board.
3) Add solder to the pads on the adapter PCB.
4) Place D1 Mini board on the pads and heat from below with hot air.
5) Once it settles from the solder melting, it's good to go.

Allows bare ESP module to be programmed from Arduino IDE or using ESP-tool. Woot!

Great idea!!!

Would be cool to still install the headers on the main board to test the flashed chip when it's done.

Hmm... adding headers is definitely a good idea. My original thought was just to make efficient use of the some parts I had. :) But adding a header, even one that matches the original packages isn't a problem. Maybe for a next revision.

Might make lining it up easier too.  :)   Definitely going to put one of these together.  Thanks!

It's a bit of an overkill (you really only need 4 pogo pins and an usb2ttl), but I like the idea.

Nice idea with putting the pogo pins horizontally, I might steal that.

But you need 4 (?) Resistors to pull stuff up and down on pins, too. So if you want to burn modules and send them away, it might make sense to have all of them.

Good point.
