# Quickstart

First step is to check the [Kit contents](https://r2djp.gitbook.io/astropixels/getting-started/kit_contents) to make sure nothing is missing, and to familiarise yourself with the terminology used.

## Wiring Up

The headers on the main breakout board are all labelled to show what they connect to, and there is a label at the end to show which row of pins is what

* S - Signal/Data
* V - Voltage (5v)
* G - Ground

Make sure that the S,V, and G pins are connected to the correct pins on the light boards.

## Recommended Cable Lengths

These cable lengths should be good if you mount the breakout board on the back of the RLD. The mounting holes are designed for this.

* Breakout board -> RLD = 1 x 10cm
* Breakout board -> FLD = 1 x 30cm extension + 1 x 10cm
* FLD -> FLD = 1 x 10cm
* Breakout board -> FPSI = 1 x 30cm extension + 1 x 20cm
* Breakout board -> RPSI = 1 x 30cm
* Breakout board -> THP = 1 x 30cm extension + 1 x 10cm
* Breakout board -> RHP = 1 x 20cm
* Breakout board -> FHP = 1 x 30cm extension + 1 x 30cm

## First Power

For testing, simply plug the ESP32 board into any USB socket. If powering from the screw terminals make sure it is a clean 5V supply. (ie, don't use a bunch of AA batteries to 'approximate' 5V)

{% hint style="warning" %}
Whilst it is fine to use the USB connector for initial testing, they are fragile so shouldn't be used in a final install.
