I bought one of these about a year ago, set the jumper for 5v. I don't recall that there was a warning at that time. This week the unit stopped working. I ordered a new one, and when I was installing it there was the following warning in the hookup guide:
"Danger! Adding a solder jumper will bypass the 3.3V voltage regulator, you will be powering the board at 5V. While most of the components on the board can handle 5V, the 16MHz crystal oscillator is not. It can only handle 3.3V. You would need to find a way to cut the trace connecting to the 16MHz and 3.3V voltage regulator in order to reroute 3.3V to the 16MHz crystal oscillator's circuit. ".
I assume that is why my board failed. Given that there are no instructions as to how to cut & reroute the traces, am I correct in assuming that this board cannot operate with 5v after all? Can I get a replacement for the one that failed? Thanks
No public wish lists :(
