Hi, I new here. I was require to use a PIC Chip for a project. I
need more info about it.

What is the different between http://www.parallax.com/detail.asp?
product_id=BS2-IC and http://www.parallax.com/detail.asp?
product_id=27290

Correct me if I'm wrong. BASIC Stamp 2 OEM Module is everything is
inside ready to program through the serial port, which BASIC Stamp 2
Module (Chip Only) require a trainer board to program it. Yes or no?

For the "BASIC Stamp 2 OEM Module" once the instruction is write in
the EEPROM memory. To use it in a standalone do I just add 5V to vdd
and Vss for ground?

Thank you

    The first difference is pin-out. The BS2 is
    a 24-pin 'DIP' (Dual in-line package). It plugs
    in to a board and takes up little space. There
    are several prototype boards available that it
    plugs into, for completed projects.

    The OEM package has a 'SIP' interface on it.
    It also looks like the programming connector
    is built-in on the OEM version, where you are
    right, the 24-pin DIP requires a few wires to
    connect to a DB-9 connector.

    The OEM package has a full LM2940-5 regulator
    on it -- which means the package is probably
    good to 1000 mA, where the BS2 is more limited.
    You'll still have to fabricate a connector for
    power, though.

    Still, what you have said seems to be correct.

    You should know that the BS2 is only nominally
    a PIC processor. True, it uses a PIC, but that's
    to implement its PBasic language interpreter.
    And yes, the PBasic program is compiled by the
    IDE into tokens, and stored in the on-board
    EEPROM, so it runs when power comes up. It's
    a very nice package, but you may want to check
    with your instructor if it meets his requirements.

    To power it, you can put 6V to 12V on VIN, or
    +5 V on VDD. Of course, Ground must also be
    connected to VSS.

    The two products are functionally the same (in terms of embedded
    control). As you point out, the BS2 module is needs to be placed in a
    circuit to provide power and programming connections. With the OEM
    module, you can plug into a breadboard, provide power (it has an onboard
    regulator) and then plug your programming cable right into its DB-9.

    If you just want to workout projects on a large solderless breadboard,
    the OEM module is an excellent way to go. If you ultimately want to
    enclose the BASIC Stamp in a finished project, the standard module is
    probably the better choice.

    Correct me if I'm wrong. BASIC Stamp 2 OEM Module is everything is
    inside ready to program through the serial port, which BASIC Stamp 2
    Module (Chip Only) require a trainer board to program it. Yes or no?

    For the "BASIC Stamp 2 OEM Module" once the instruction is write in
