  MAX7219 Dot Matrix Module Control Display Module DIY kit Cascade

  Rep, this is just one module with 8x8 LEDs right? So we need 4 to make something like the demo picture?

    Thank you for your info!

    Yes, this is just one module with 8x8 LEDs right.
    If you'd like to make the same one, you need 12pcs. :)

    By the way, this item is with STM8S003F3 MCU which the data storge space is 1K.
    Then the qty of the module depends on the space of your characters.

    Hope above info could help you.

    Best regards,

  Wow, what a dream piece for terrorist. Is this the same one they used for IED (improvised explosive device) in mid-east? Anyway, it is really useful as a replacement remote for an old garage opener.

    Mobile phones are also used. So we are all potential terrorists.

    Thank you my friend.

    Now if I wire together the
    4 Channel Wireless Remote Control Kit ($3.70)
    with the
    4 Channels 5V Relay Module ($6.60)
    and power them with a
    5V Power supply module ($1.85),
    I can control 4 devices from the palm of my sweaty hand…

    That really is in bad taste, hotwinter.

    As greenpossom posted, most of us has the makings of the trigger for a explosive device in our homes (TV remote, radio controlled toys & gadgets, phones, laptop, or any transmitter device).

    Only someone wanting to be a martyr would want set off a device within the quoted 50m maximum operating distance - in which case there is little need for this complexity.

    If you have ever seen disfigured corpses in a war zone like I have, you may think differently.
