The MCP2200 is a new USB to serial converter chip from Microchip. This breakout board brings all the pins to bread-board friendly headers.
- USB CDC virtual serial port interface
- Secondary HID configuration interface
- Up to 8 additional IO
- TX/RX indicator LEDs
- All pins to bread-board friendly header
The MCP2200 is actually just a PIC 18F14K50 programmed with a firmware, but it's slightly less expensive than the PIC alone.

Issues with the MCP2200
Windows XP issues: SP3 or later required!
This is a composite USB device (serial port and HID configuration channel). A composite serial device will only work on Windows XP SP3 and higher. The device will connect and the transmit LED will blink (if configured) but no data is actually sent or received. Read more here and here.
RTS/CTS are handled locally on the chip!
The CDC serial device specification doesn't include CTS or RTS. The firmware in the MCP2200 handles the RTS and CTS signals internally. This means it probably can't reset your Arduino for programming.
