Re: [Gumstix-users] TTL UART to Summit Board

Have you looked at the FTDI solutions. http://www.ftdichip.com/ You can get 
their modules from digikey. Modules are fairly small but with certainly 
give you the confidence in proof of concept from which you could spin a 
smaller dedicated solution. Design schematic are availble for their 
modules.

Subject: [Gumstix-users] TTL UART to Summit Board

Hi All!   
 I've got a GPS 
(http://www.sparkfun.com/commerce/product_info.php?products_id=465) 
communicating over UART TTL (it's actually a bit below TTL), which I want 
to connect to the Summit board with minimal components - this is for an 
embedded application, so size is crucial.  Right now I have the GPS output 
level-shifted, then translated to RS232, and sent to the computer over a 
serial-to-USB connection, so I can translate from any of the following: 
GPS's slightly-below-TTL output TTL RS232 
 To any of the following (ie, any input to the Summit Board): I2C SPI Male 
5-bin Mini-B USB 
 Anyone got a suggestion that doesn't involve 5+ stages (my best solution 
thus far)?  All the UART to USB modules (ie Sparkfun: 
http://www.sparkfun.com/commerce/product_info.php?products_id=199) that 
I've found so far all have female connections, and I haven't found a good 
male-to-male adapter either... 
 Thanks so much for the help! -Kim
