Documentation for the Multiple 8-Relay Addon EMO-R8



  • Hi,

    I am thinking of using the Multiple 8-Relay Addon EMO-R8 board for one of my products. I have multiple I2C devices connected to the same I2C bus (LCD, keypad and unipi) and need more relais to switch the HW connected. Is it possible to provide documentation for the Multiple 8-Relay Addon EMO-R8 so I can check there will be no conflict in the I2C addresses.

    Thanks!

  • Hello,

    unfortunately we do not have any more specific documentation for this module, however it is the same IC as on the UnIPi itself.

    So 0x20 is taken by UniPi and then you can choose the address in range 0x21 - 0x27.

  • Thanks Tomas, That should be sufficient!
