Adafruit USB/Serial Converter

This USB cable seamlessly integrates a DB9 serial port into your computer or laptop, making it a versatile tool for connectivity. Fully compatible with MacOS X, Linux, and Windows, this cable harnesses true voltage doubler/inverter technology, delivering approximately +-6V RS232 serial, perfect for legacy devices like GPS units and handhelds.

Experience improved performance with our FTDI-chip-based adapters, offering enhanced reliability and compatibility. Equipped with three visible LEDs, it includes a power LED to confirm connection and RX/TX LEDs to assist with connection diagnostics.

Tested extensively, it excels with bit-bang serial programmers and adapters, although note that the USB interface does incur a higher overhead than hardware serial ports. Favorable over the older PL2303 converters, ensure utilizing the latest drivers from the Prolific Website for optimal performance.
