The Adafruit FT232H Breakout turns your computer into a versatile interface for hardware protocols. Using the FTDI FT232H chip with its multi-protocol synchronous serial engine, you can communicate directly with I2C, SPI, JTAG, and serial UART devices — plus read and write digital GPIO pins — all from your computer over USB, with no microcontroller required.

This is especially useful for rapid prototyping and testing with Python. You can drive OLED displays, read sensors, flash LEDs, and more directly from your computer without needing to write and upload firmware to a separate board. The breakout includes an FT232H chip and an EEPROM for on-board configuration, and works with Mac, Windows, and Linux.
