I just thought I'd let people know about an issue I'd run into:
With DIO, code executes somewhere in the neighborhood of 30-50% slower (I haven't timed it precisely) vs QIO. And you can't really tell if the board you bought has it wired as QIO or DIO until you try to flash it (the QIO capable ESP12 modules have "QIO" printed on the underside, but you can't see that if they're soldered in).
For my pingpong light controllers, I realized this after I had a bunch made with DIO modules (they have to all run at the same speed, and I'd like the QIO ones to run faster), so I've been taking the DIO modules off of my WeMos D1 Mini's with a torch and soldering a QIO one in it's place....
