    Involvement:General (knows how to use it) - Ownership:more than 1 month


    Good shematic, good build quality, working soft.

    Very cheap for this equipment.

    shematic is standart and simple using FTDI FT232RL chip, 7 bipolar transistors and LM393 IC.

    FT232RL is very powerful chip. It along prices about $5.83 in my country.


    It is not working with my car. B-((.

    Device is working and it answers for software. When I trying to connect to MCU in my car somthing is "clicking" (I think it is some relay) and no answer from MCU.

    I tried a different software but with the same result.



    ...I'm not too upset, because I have already said that the chip, which is in the adapter is very versatile and powerful and I can use it in my projects. Here are just some of the characteristics of the chip (and it working properly):

    Single chip USB to asynchronous serial data

    transfer interface.

    Entire USB protocol handled on the chip. No

    USB specific firmware programming required.

    Fully integrated 1024 bit EEPROM storing

    device descriptors and CBUS I/O configuration.

    Fully integrated USB termination resistors.

    Fully integrated clock generation with no

    external crystal required plus optional clock

    output selection enabling a glue-less interface

    to external MCU or FPGA.

    Data transfer rates from 300 baud to 3 Mbaud

    (RS422, RS485, RS232 ) at TTL levels.

    128 byte receive buffer and 256 byte transmit

    buffer utilising buffer smoothing technology to

    allow for high data throughput.

    FTDI?s royalty-free Virtual Com Port (VCP) and

    Direct (D2XX) drivers eliminate the

    requirement for USB driver development in

    most cases.

    Unique USB FTDIChip-ID™ feature.

    Configurable CBUS I/O pins.

    Transmit and receive LED drive signals.

    UART interface support for 7 or 8 data bits, 1

    or 2 stop bits and odd / even / mark / space /

    no parity

    FIFO receive and transmit buffers for high data


    Synchronous and asynchronous bit bang

    interface options with RD# and WR# strobes.

    Device supplied pre-programmed with unique

    USB serial number.

    Supports bus powered, self powered and high-

    power bus powered USB configurations.

    Integrated +3.3V level converter for USB I/O.

    Integrated level converter on UART and CBUS

    for interfacing to between +1.8V and +5V


    True 5V/3.3V/2.8V/1.8V CMOS drive output

    and TTL input.

    Configurable I/O pin output drive strength.

    Integrated power-on-reset circuit.

    Fully integrated AVCC supply filtering - no

    external filtering required.

    Great set of options...


    Despite the fact that I could not take advantage of this adapter, according to his scheme, I see that it is sufficiently reliable. Moreover, that car, for which I bought the adapter I already sold and is now going to use this card in my homemade. I think this is a very good buy for the money ...

    Yes, I almost forgot, if you want to use this adapter with old machines BB Group, you'll have to buy one more thing this adapter:
