Cant Recover ItsyBitsy 5V 16MHz

Post by DanBeyond »

Hi All,

I'm working on a project where I'm making a basic LED Driver using the WS2812B LEDs and the ItsyBitsy 5V 16MHz. Something happened and my ItsyBitsy has gotten into a state where it wont show up as a COM port in Windows 10. I have tried the boot loader reset described here:
https://support.arduino.cc/hc/en-us/art ... rduino-IDE

I see the on-board red LED pulse when bootloader reset mode is active but the board appears to time-out before the programmer is done loading a new file. This seems to hold true even when uploading a blank file.

I don't have easy access to a programmer, but I do have access to more Arduinos. I have managed to get two of my boards into the same state and am hesitant to try with a third for now.

What can I do to get myself out of this situation? Both of these board were working at the beginning of the night and appear to bricked.

Thanks,
Dan
