    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    PCB board quality is well.
    It could be powered direct from USB.
    It has onboard 3.3v power seurce so You can use it in low voltage applications.
    Most of IO could be used in your application.
    It also has 4 buttons and 8 indicator LEDs.
    It has software USB bootloader, so You just need mini-USB cable and BootloadHID Software (it could be downloaded from anywhere).

    Cons:

    Screws, shown on photos not included.
    JTAG debug interface is locked by fuses, so you shoud unlock it via SPI first, but it is not a real cons.
    Working frequency could not be 16MHz with this MCU. It is only 8MHz.

    OtherThoughts:

    How to start:
    Run BootloadHID Software.
    Connect PCB to PC via mini-USB cable
    Press and hold button S1
    Press and release RST button.
    Click Find Device button on the BootloadHID window.
    Open *.hex file and download it to Minimum AVR System Board

    Bottomline:

    Could be used in a wide range of applications.
