Introduction
The Kitronik ZIP Arc large 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. 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
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.
DOUT pin is for the data output to more
ZIPs.
+5V & GND Voltage supply connections.
Extension
To connect more ZIP Arc’s together, place two boards end to end with DIN next to DOUT. Solder all four of
these connections. For further information for Zip Arc extension visit

Application
A typical application for the ZIP Arc, 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
