RS-232 USB madness


If you’ve been amused by the lengths people go through to speak to a serial device these days. [timmeh] just took the cake. He build his own frikkin’ tiny RS-232 to USB interface with the diminutive SIL CP2101. The package on it is QFN-28 (If PLCC is Darth Vader, QFN-28 is his mean little brother.) That said, if you prefer to work with stuff that talks TTL or RS-232, this could be a handy add-on to pop a USB port on your project. (Oh, look, they have samples…) Sure, we’ve beaten the serial connections to death, but they’re so handy we just can’t resist. It may be a decent way to add a serial port to your laptop. (Picture this: dell’s bluetooth cards are usb devices – you could add one of these without even voiding your warranty.)
