Customer Questions & Answers

  • By  Geoff Jan-08/2017 01:01:11

    Which Arduino is it compatible with, is it the 3.3V Arduino or the 5V Arduino? In other words, what is the input voltage & current?


    Hello Geoff,

    Thanks for your inquiry.

    The input voltage is 5 V.

    The current is too small which is calculated by mA.

    Have a nice one.

  • By  Nelson Dec-05/2016 02:12:26

    Does this relay comes with a flyback diode or some sort of peak protection from the coil?


    Hello Nelson,

    Thanks for your inquiry.

    There are a flyback diode and some sort of peak protection from the coil.

    Have a nice one.
