Parallax has designed a USB to Serial (RS-232) adapter that is compact and economical. This adapter works with all of our products. If you don't have a serial port on your machine, this is an easy solution. To use this adapter simply plug it in to your machine's USB port using a USB A to mini B cable (#805-00006). Next point the operating system to the appropriate driver. Then add the driver port to your Parallax BASIC Stamp module, Javelin Stamp module, or SX-Key software IDE and you're ready to program with a virtual COM port.

Parallax designed it using the latest FTDI chip (FT232RL). This adapter supports multiple operating systems. FTDI provides fully functional drivers, maintaining and improving them as operating systems change (such as Windows).
