I have one of the Panthers, and in testing I am having issues with the board reading my SD cards (I have tried 2 different, 1 SDHC 32GB, and 1 2GB SD). I have tried 2 different cards, and I am having a lot of single LED flashes (SD card read issues). Every once in a while I can get it to read the card, but it is inconsistent. I have attached pictures of the front and back here.
