Wouldn't it be cool to drive a tiny OLED display , read a color sensor , or even just flash some LEDs directly from your computer? Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakout board!
What can the FT232H chip do? This chip from FTDI is similar to their USB to serial converter chips but adds a 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I2C, serial UART, JTAG, and more! There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, and more. The FT232H breakout is like adding a little swiss army knife for serial protocols to your computer!
This chip is powerful and useful to have when you want to use Python (for example) to quickly iterate and test a device that uses I2C, SPI or plain general purpose I/O. There's no firmware to deal with, so you don't have to deal with how to "send data to and from an Arduino which is then sent to and from" an electronic sensor or display or part.
This breakout has an FT232H chip and an EEPROM for onboard configuration. You can read tons more about this chip from FTDI's page and check out our tutorial on how to get started and use our Python code to control the FT232H with Mac/Win/Linux.

Programming the FT232H breakout in Python is pretty easy. I was able to write a program that controlled my DAC and implemented my project in about 130 lines of python code.
The board ships with headers, but without them soldered, so be prepared to solder the headers yourself (this is not difficult if you have the appropriate tools). The reason they ship the boards without headers soldered is because different people may want to terminate the board differently. In my case, I had some 90 degree headers on hand that I used instead of the supplied straight headers.
The board is well-constructed and worked well. My project worked flawlessly.
This + the code on adafruit is one of the easiest ways to use python to interface with embedded devices and sensors through the USB port. If you want the best USB to UART converter buy this one. Yes you can get the same thing for cheaper elsewhere, but they have excellent tutorials and are worth supporting.
