Re: Interesting Chip/Module

I have been playing with some FTDI FT2232D USB chips that are pretty
interesting. They are capable of providing a pair of UARTs on a USB
cable and they are also capable of providing several varieties of
parallel access. FTDI has downloadable libraries and drivers for UART,
SPI and I2C as well as simple parallel, uC bus emulation and a couple of
other parallel configurations. I have used them as UARTs and simple
parallel access. The drivers work pretty well and the libraries that I
have used all work pretty well.

The newer modules, based on the FT232RL are even simpler. They don't
require a external crystal, although they only have a single UART
port.
Sparkfun sells a breakout module for only $14.95

There is also the parallel version:
