    I have read a lot of negative messages in this thread about the OpenServo board.

    Question: Is this board ready to use? (no firmware update, nor compiler,….)

    And in case of “this part is useless”…..is there any alternative out there? Best in combination with OpenEncoder and 360° rotation.

    Hi,
    I didn’t find any information about this module like
    - baude rate (4800, 9600,…)
    - timing
    or any C example code. :-(
    Is any example (best for arduino) available?!
    Need help
    Andreas

No public wish lists :(
