    Hello Moe,
    Thank you for writing in.
    It seems you are not talking abou #300193.
    The item #300193 is used to measuring resistance and voltage, it can’t measure current. Or do we misunderstand you?
    Look forward to your reply.
    Best regards.

    Hello Sam,
    Thank you for writing in.
    The item(B00S7YK8KS) you mention is a buck converter, it can’t monitor the power consumption.
    Do you mean you needa a device that can monitor 12 V and 5V respectively?
    Best regards.

    in reply to: TTL to RS485 #16902

    Hello Patrick,
    We are not sure whether the item (B01KFLESUG) can be used with arduino.
    You may need to add a USB to TTL module and drive module.
    So we can’t ensure whether is is available.
    For more question, please let us know.
    Best regards.
