    Default Do I need to buy Konnect Optical I/O Expansion Board?

    Good day!

    I have 4 step motors, 1 stop buton, 8 end sensors, 4 pneumo relay for suction cups.

    I am going to buy 1) KFLOP, 2) KStep Microstepper Amplifier for KFLOP.

    Do I need to buy Konnect Optical I/O Expansion Board?, - as amplifier for KFLOP already has optoisolated inputs and outputs.

    Hi RuslanRobot,

    KFLOP+KStep should cover all that except KStep only has 2 opto outputs. So you would be 2 short. You might add 2 additional opto isolated relays. Or some 3rd party relay driver board such as this. Or Konnect.

    I see the KStep Amplifier for KFLOP https://www.dynomotion.com/KStep.html

    It will drive 4 motors and emit heat.
    I don't understand - How to cool this board?
    Shold I buy radiator? - but I don't see the place to where it must be installed.

    Hi RuslanRobot,

    KStep uses very efficient MOSFETS (17 milliohms) so very little heat is created and the Printed Circuit Board itself is a sufficient heat sink. However if enclosed in a box some airflow through the box should be provided.
