    New version, like 12F with better antenna

  2. porkyneal (verified owner)

    Great little modules, can’t get enough of them.
    New version, same as the 12E / 12F but with a new and improved antenna design.
    Missing the bottom row of pads, however, these were not that useful (connected internally to flash I believe).

  3. marc06 (verified owner)

    Really good and small wifi card. And also a great number of IO for cheap price. Bravo!!!

    Module with 4MB flash chip. Good!
