Recent versions of Linux have the driver pre-installed. The methods described here should work in general for cables using different chips. This article will focus on the CA-42 containing a PL2303HX rev. They’re available on eBay and DealExtreme and very inexpensive. These cables have a USB to Serial TTL converter built right in. The trick is to use a Nokia cell phone data cable based on Prolific’s PL-2303. Well look no further because this article has just what you’ve been looking for. What a heart breaker! There are slightly cheaper alternatives, but a real scrooge googles on. For these penny pinching DIYers setting up an ATmega on a breadboard seems like the way to go until they discover the FTDI USB cable is $20. To be fair there are arduino clones that do lower the price a good bit, but the real cheapskates that don’t mind doing a little extra work can’t help but think they could do it for less. The Arduino board is a great way for beginners to start learning about developing software for microcontrollers however it’s cost, while a steal when compared to the initial investment required in the past, can be a little too steep for a do-it-yourselfer who wants to do things cheaply. Several good, inexpensive, purpose-built USB to serial modules are now available on eBay for around five to six dollars.
