MCP2200 Dev Board

MCP2200 Breakout Board

I included a small design for the MCP2200 USB UART chip from Microchip since the pricing on this chip is way better than that of the FTDI FT232RL chip.  Octopart has the MCP2200 $1.92 vs $4.95 for the FT232 chip. Overall the board works well and I plan to incorporate this chip into a number of other designs.  Feel free to drop me a line if you have any questions about this chip.  The schematic is attached below.

    How about a nice little board for USB RS485 should be cool.

    I hadn’t thought about that, but would certainly consider looking at this a bit more.

    Your schematic shows a voltage regulator and a 3v3/5v switch, but the datasheet says “The USB transceiver obtains power from the VUSB pin, which is internally connected to the 3.3V regulator.”

    Whats going on there?

    Thanks

    The idea was to be able to power external circuits from either 5v/3v. The Vcc option is chosen by the switch. The chip will always be powered by the 5v from the USB cable.
