Mounting options for such ESP modules?

Hi

By mistake I ordered some “naked” ESP-32 S2 modules:

An idea how I can use them easily ? as I don’t have hardware to solder pure SMD components (have a regular thin electronic iron solder).

Thanks for tricks :wink:

Haha… not you could try to search for a board like these

But given the price I would order ones with pins already attached… it’s not worth the hassle.

Yep I searched already for such boards but can’t find any compatible with ESP32-S2, probably too recent I guess ?? And in all matters I have no idea how to solder the ESP on the board as contacts are under the module so inaccessible once installed on the board :confused: I’m afraid these modules can only be soldered with an industrial soldering machine…

You could solder it with solder paste and hot air gun, but you’d need those two items and also suitable PCB…
I would simply solder tiny wires on those pads (so that they protrude out of board itself) and make another board with pins beside the board (or use euroboard).
