I have a gumstix basix 400 up and running. I would like to interface the GM862 device to one of the serial ports. As I haven't messed with logic levels much below 5V (hope this doesn't date me) I have a question:
Can I take the GM862's TX/RX lines (2.8V) and directly connect them to the gumstix's RX/TX lines (3.3V) without level translation?
Just don't want to ruin perfectly good hardware due to 0.5V...
Any help would be appreciated.
