FT232R USB/Serial Bridge/BOB
You’ll be surprised first and foremost by the size of this USB/serial converter — no larger than the moulded plug on a USB cable! And you’re also bound to appreciate that fact that it’s practical, quick to implement, reusable, and multi-platform (Windows, Linux, etc.) — and yet for all that, not too expensive. Many commercially-available FT232R-based modules are either too expensive, too bulky, badly designed, or all, which is why this project got designed in the form of a breakout board (BoB).
