Introduction

The Kitronik ZIP Circle is a set of 12 RGB LEDs, 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. This

results in 16,777,216 possible output colours. Multiple ZIP LEDs can be connected to produce longer

strings/strips/circles.

The LEDs used are based on the WS2812B part. They can also be coded in the MakeCode Block/Javascript

editor with the NeoPixels blocks.

Circuit Overview

 This circuit has 12 programmable ZIP LED’s chained in series.

 There are 8 connections (4 on each end of the PCB).

 DIN pin is for the data input.

 +5V & GND for connecting Voltage supply to the PCB.

Application

A typical application for the ZIP Circle, connect it to the ZIP Halo (Stock Code: 5625) and use the extra LEDs for customisation. For further information and details refer to “Using Kitronik ‘ZIP’ LEDs” document from
