  • Not sure why there are two separate versions of these FTDIs. As has been previously pointed out, there is a 3.3V pad and a 5V pad, with the output in the center. The only difference between the FTDIs seem to be where the trace is coming from.

    I had bought a 3.3V FTDI and I need it to supply power to a 5V Arduino Pro Mini. Per bboyho's post, I cut the 3.3V trace and created a solder bridge between the 5V and center pads. It worked fine, but I still needed 3.3V. So, I mounted a small switch to the FTDI and did some really fine soldering to the pads. It's not pretty but it works like a charm.


No public wish lists :(
