Re: [Paparazzi-devel] Connecting Navilock NL-652ETTL

[David Conger]

Great,

You've discovered another use for the FTDI Utility for me :)

For the next version I see about adding a 5 pin connector where the 4
pin one is and have it work for programming GPS boards.

Glad to hear you got it working.
