Re: [Gumstix-users] 5V input

[Rob B. <ro...@gm...>]

I should have been more verbose in my first post.
It's an IR receiver module that will be outputting a 0.2-4.5V digital square
wave. This will be connected to a UART port and read as a serial input. It
will be receiving at about 1.2Kbits/s.
Thanks for the help.
