    I have in my possession a b.mini (X2? White PCB, 2 rows of SMD RGB LEDs), that I got second hand a few months back. The board has been a joy to have and was working great, but has lately started to act up lately, and has finally reached a point where it seems to experiencing severe problems.

    It started with me noticing out of the corner of my eye what looked like the RGB LEDs flickering off and then off very quickly, almost like the keyboard had lost connection for a brief moment. This was confirmed when I began noticing that sometimes the keyboard will disconnect for a second or so a time (i.e. I’ll be typing and it stops recognizing keystrokes).

    Fast forward to today/tonight: I’m now getting very frequent connection drops (several times while typing out this message), and the LED that is soldered onto the ESC key (it seems to be some kind of status/indicator light) is flashing constantly. I’ve tried a computer restart, as well as a few simple changes in BootMapper–oh, on that note, for a bit, I couldn’t even connect to BootMapper; I got an “Error setting action” error.

    I’m fearing that the PCB might have something going wrong with it, but am hoping there may be another answer 🙁

    Thanks!

    I think you should check soldering.
    The problem you described is generally due to bad soldering.

    I guess there would be some electricity short or loosely attached parts.

    Could you tell me your order number?
    (If you buy it from someone, ask him.)

    And can you try upload new firmware, ps2avrGB_firmware_V1.1_160228.zip?

    Hi,

    Thanks for getting back to me! I tried flashing the firmware, and although it seemed to flash successfully, the issue persisted as described.

    I spoke with the guy I got it from, and he says the order number is #770.

    I’m starting to agree that it seems likely to be a soldering issue.

    Hi Please check around the soldering parts of bad switches and in-switch LED.
    (This order didn’t contain any in-switch LED option.)

    I’m sure you can find it.

    Thanks.
