PREVIEW: Sigfox IO Evaluation Kit

    Description

    This evaluation kit shows how easy it is to do applications and product design based on our SIGFOX-MOD1 module.
    It features 8 digital input channels where you can connect any type of potential free contacts.

    Buttons, switches, relais contacts, reed contacts and so on.

    The inputs are continuously monitored and whenever one of them changes its  value, a sigfox frame is assembled and transmitted containing the current state of all inputs.

    It is internally running on 3.3V and includes a LDO, so you can feed it with a voltage from 3.6V to 5.5V. So you can run it from a 5V cell phone wall plug, or a USB Power bank, or a primary cell battery pack or some special 3.6V primary cells.
     
    Best suited for IoT devices, that monitor existing equippment that has some signaling contact, or opening and closing of doors/windows/shelfs/boxes.

    What's in the bag?

    coming soon

    A simple button operation

    Here a press button is connected from one input channel to GND. When it is pressed you see on the spectrum analyzer in the background, the transmisson of the sigfox frame. Hence 3 repetitions for each frame.

    But why do we see 6 peaks showing up?

    Because also releasing the button leads to a change in the input signal and also triggers a tranmission, which is queued. So in fact we see 2 sigfox frames being sent.

    Other connection options

    There are also other options for different connectors possible. Here are some examples:
