Quoted from arcadenerd925:
True, but mine has the 7.5v boards, I only had one blow and the replacement one has the tiny daughter board filter/buffer. havent had a problem since (and that was a few years back give or take)
The first run ones were the 5v boards right? I would steer clear of those.
7.5v were an interim solution when they didn't know what the real problem was. The final versions are back to 5v with the buffer board and are fine. But again, if he wants to be safe, just get a Ruby Red version. The problem was solved by the time that hit.
