The impFactory™ is Electric Imp’s recommended factory BlinkUp™ fixture. This off-the-shelf factory appliance allows your assembly line to instruct production devices to run your factory firmware. It does this by sending the factory WiFi credentials and a factory enrollment token to each production device’s on-board imp module optically via an LED.


To use an impFactory, you use BlinkUp to add the fixture to your Electric Imp account; you develop factory firmware for it; you assign the impFactory as a factory imp; and you use it to configure production devices as they are manufactured. The impFactory is a great option for all imp-enabled products going to manufacturing because it can be purchased directly and includes many useful features:

  • Front-panel button for triggering factory BlinkUp.
  • Front-panel BlinkUp emitter status indicator.
  • LCD and keypad to provide options for more complex tests and/or operator interaction.
  • Front-panel red and green LEDs can be used to display test Pass/Fail information.
  • Rear Panel:
    • Mini USB for power.
    • RS232 serial port allows the impFactory to drive other assembly line equipment, such as a label printer.
    • Foot switch port allows an external switch to be used as a BlinkUp trigger.
    • LED port to drive assembly line factory BlinkUp emitter
    • Ethernet port for wired networking — WiFi also supported.
    • USB A port for USB host.
    • Photosensor for impFactory configuration by BlinkUp.
    • impFactory BlinkUp status LED.
