Each of our new ZIP Circles has 12 individually addressable RGB LED’s. Each LED can be controlled independently and all LEDs are connected using the same three wire bus.

Each LED can produce a full spectrum of colours independent to all of the other LEDs on the bus. Each ZIP LED has a Red, Green and Blue element within the LED, and each of these can achieve 256 levels of brightness. This results in 16,777,216 possible output colours. Multiple ZIP LEDs can be connected to produce longer strings/strips.

The LEDs used are based on the WS2812B part which is compatible with any WS2812B driver code. They can also be coded in the MakeCode Block/Javascript editor.

 

Features:

  • Simple 3 wire connection for all LEDs.
  • Compatible with any WS2812B driver code.
  • They can be coded with the Microsoft MakeCode Editor for the BBC microbit.
  • Integrated reset circuit.

    Answered by the admin HI Sam,

    In theory yes the ZIP LEDs should be able to respond to most micro controllers provided they are the correct voltage. We have not get any guides and have not tried it specifically though I am afraid.

  2. Do these have to be wired up to a mains supply or will they work using a 12v battery? Also are they able to produce a warm white colour?

    Answered by the admin Hi Jack,

    Thank you for your question, you should definitely not connect it to a 12V supply. These are run from 3.5V to 5V and draw 50mA so would not really be suitable on mains supply.

    They don't produce a warm white colour unfortunately.

    Best Regards

  4. How can I connect the ZIP Circle using breadboard jumper wires like you have in the third picture (it only shows the front)?

    Asked by Baptiste Guittet-Carriere on October 19, 2018 12:00 am
    Answered by the admin Hi, On the back of the board there are 4 solder pads, to enable you to place this into a breadboard you can solder pin headers onto the back of this, this is what we did to create this photo and also how they are supplied in the ZIP Add-on for the inventor's kit . In this kit we used these , and snapped these into 5's.
  6. Can I connect a 4.5V battery arrangement to this directly just to light them all up at once?Thanks

    Asked by Richard on June 8, 2018 12:00 am
    Answered by the admin Thank you for your question, I am afraid not addressable LEDs will not function without a micro controller like a micro:bit to control them.
  8. Micropython equivalent code please.

    Asked by Olivier on February 19, 2018 12:00 am
    Answered by the admin Hi Olivier, We don't have any generate Micropython code for the ZIP LEDs yet. However we have some Micropython code which can be used with the :GAME ZIP 64, which has ZIP LEDs on. Any library that uses Neopixels, (Adafruits branded version of LED) would work also.
