This will fix all ESP module firmware issues. Worth the extra cost compared to buying a bare esp12. I had no problems programming with the Arduino IDE and everything works as expected. It's as compact as an all-in-one system can't get. I used large esp12 dev boards for everything but they are about twice the size. These are now my favorite boards.
