Hello,
A) The autopilot is programmed via USB using that USB mini adapter. See the silkscreen on the board there is a USB connector on there. You are correct about one of the reasons/uses for the FTDI board. UARTs communicate via TTY Serial so it's a handy board to use for communicating with many things. On the bench if you don't want to plug in the modems just plug in the FTDI board to the "serial" connector on the board. "If the above assumptions are correct then why is there a a set of pins labeled USB just above the Serial pins? " A) Not entirely correct. When you need to change the configuration you need to re-send it to the autopilot. This is done via USB (see first response). With small UAV weight is important. Also not having lots of connectors and wires. If you have a large UAV maybe it doesn't matter. Most people with small UAV (MAV) will do away with the connectors and run wires just long enough to get from A to B. I would cut the rather large servo connectors off and solder the wires so the servo has a 3-pin molex as the only connector. Remember the ESC DOES NOT USE THE POWER PIN (5v). So, when wiring up the ESC only use the signal and ground wires. For the Rx or PPM board the 5-pin cable is pre-wired and should be easy to figure out. -David On Apr 29, 2009, at 6:34 PM, Michael Caughey wrote:
