With our board we are solving issues that have been in the wild for quite a while .. issues
like:
Being in an unproductive, messy environment - full of sensors, jumpers, bread boards and
cables. Our CrowPi solves it by offering an all-in-one board with on-board necessary
sensors for learning and rapid development.
Being unable to start using Raspberry Pi or Python Coding due to the complex, old
fashionable learning methods. We offer 21 lessons to get started with hands-on, detailed
examples that anyone canmake.
The Raspberry CrowPi Kit can be used as laptop, gaming console, IOT project, studying,
making, prototyping and more! The imagination is the limit.
You can fit Raspberry Pi 3 into the CrowPi and extend support of sensors and modules
using the on-board breadboard.
We'd like to thank you again for supporting us and purchasing your first CrowPi Develop-
ment board. We can't wait to see what you'll make with it!

The CrowPi Safety Notes and warnings
Elecrow puts their customer's safety and security at the first priority, for the same reason
Elecrow doesn't use dangerous materials while manufacturing, and we follow extremely
strict QA tests to make sure the highest quality product will be shipped to our customers.
The CrowPi is a safe-to-use product with 5V input by power supply. Even though it's
completely safe to use it under normal circumstances there are a few rules that parents
should be aware of when buying this product for their children.
* Children should be under parent's supervision while using such a product, the product
contains small parts which might cause chocking to small children if swallowed.
* The relay module supplied inside our CrowPi board should ONLY be used within the
breadboard circuit designing, standing with 3v/5v power supply and SHOULD NOT
under any circumstances be used / connected or wired to a 220v/110v power plug like
light bulb, air conditioner etc …
* We care about your children's eyes and health just as you do, we do not recommend

Initial Installation
Pre-installation requirements
Before diving right into the CrowPi Initial installation guide we'd like to confirm you have
everything that is required in order to make the installation process as smooth as possible.
Please go through the following checklist and make sure you have it all
Note: These are not optional. They are all necessary for the installation process.
Official Elecrow CrowPi Board
CrowPi Power Adapter
Raspberry Pi 3
Micro SD Card (Highly recommended
Class 10, With high Read/Write speed)
8

Micro SD Adapter (To be able to
connect to your PC / Laptop)
Mouse + Keyboard (Can be
bluetooth as well as USB)
If you've confirmed you have the above items, You're ready to go!
Downloading the CrowPi Image
The Raspberry Pi uses an Linux-based operating system in order to function properly,
it uses a Micro-SD card to boot the operating system into a use-friendly environment to
enable customers like you to code and make amazing things.
In the following steps we'll go through downloading the Raspberry Pi Image that we're
going to use.
In order to make the whole process much easier and user-friendly, we've created an
image based on the stock Raspberry Pi Raspbian Image with all the necessary drivers
and installation that will help you get you started right away without hassle .
You can either use this method and burn our Image or use a stock Raspbian Image
from the Raspberry Pi website and then install all the drivers manually.
We highly recommend the first method. To clarify, We didn't modify or add any
thing unnecessary to the image, all the modifications are for the pure purpose of
9

making our CrowPi working perfectly with the Raspbian OS. If you don't have any
advanced knowledge with compiling packages from source / getting around
Linux OS - We strongly recommend downloading our Image.
To download our Image, go to the following link on your favourite web browser:
https://www.elecrow.com/download/crowpi/crowpiV1.zip
And download the “.img” (image) file that contains the CrowPi Raspbian OS.
To download the stock Raspbian image, go to the following link on your favourite web
browser:
https://www.raspberrypi.org/downloads/
And download the official Raspberry pi Raspbian OS or any other Raspberry compatible
image that works for you .
Burning the image into an Micro SD Card
After you've successfully downloaded the image, you should have a file called
“<file_name>.img” while “<file_name>” can depend on where you downloaded from,
either Elecrow website or the Raspberry Pi Official website.
The file extension should be “.img” or “.zip” if it’ s an “.zip” you should extract it to have a
file file extension “.img” .
In order to extract it,download the software “7zip” for Windows or “the unarchiver”
for Mac OSX:
Windows: http://www.7-zip.org/download.html
Mac OSX: http://wakaba.c3.cx/s/apps/unarchiver.html
After you successfully confirmed you have the file, the next step will be burning the
image into your Micro SD card.
In order to burn the image, we'll need a tool called “Etcher” , Etcher is a graphical Micro
SD card writing tool that works on Mac OS, Linux and Windows.
You can download Etcher for your Operation System here: https://etcher.io/
10

After downloading and opening Etcher you should see something like this:
Follow the following steps:
1) Click the “Select Image” button and select your .img file which you downloaded from
either Elecrow Website or Raspbian official website
2) Click “Select Drive” button to select your Micro SD Card that you would like to burn the
image on (if Micro SD Card inserted, Etcher will do this step for you automatically)
3) Click Flash Button to flash the image, wait for it to finish and we're done!
Attaching the Raspberry Pi to the CrowPi Board
After finishing the burning process it's time to disconnect the micro SD card from the PC
/ laptop and plug it into the Raspberry Pi.
Note: Make sure to follow the following steps carefully, don't apply extra pressure or
strong force over the cable as you might damage the pins.
11

Note: First of all, we should have to plug the cable first, then mount screw . You
can put the unused cable under the board.
Raspberry Pi 3
HDMI Port
USB 2.0
After successfully plugging back in the Micro SD card, we'll need to lay the Raspberry Pi
over it's location on top of the CrowPi board.
Afterwards, we'll need to plug it in by using “rainbow” (flat) cable. We'll first carefully plug
it into the Raspberry pi making sure it covers the exact pins of the raspberry pi and very
importantly doing it carefully not to damage the Raspberry Pi pins.
The second step will be plugging the “rainbow” cable into the CrowPi board.
We'll take the other end of the “rainbow” cable and carefully plug it directly into the board
making sure it covers all the pins and placed at the right spots.
Raspberry Pi 3
12

And … We are done! Well … almost!
To make sure that the Raspberry Pi won't move during your rapid development we will
need to attach it using screws, the Raspberry Pi contains screws to be attached to the
CrowPi board, take a look at the following picture for reference:
Make sure to attach them tightly for your Raspberry Pi safety.
Last thing will be to plug the CrowPi board into power supply, it's highly recommended
to use the power supply we supply with the board, but also any other power supply like
micro-USB / Battery will work as well.
Power Port
13

First time booting into the Operating System
After We've prepared everything and plugged the power on, if the Raspberry Pi doesn't
turn on by itself - it means the power button isn't pressed.
After powering on the board by clicking on the power button, the Raspberry Pi should
load the operating system automatically. Give it few seconds up to one minute to load
until you'll see the desktop environment and you'll be ready to go
Power Button
USB Powered-Easy
and Convenient
14

Congratulations!
You've officially got your CrowPi up and running.
You might have realized that you have no way to control the desktop environment
except for the 7 inch touch screen … let's get it solved by plugging in a keyboard and
external mouse.
We can do it by simply plugging in a USB keyboard and USB mouse
15

Or connect Bluetooth keyboard and mouse using the touch screen with the bluetooth
configuration
Last thing will be connecting to a local wifi access point or using Ethernet cable if that
works better for you (both are optional)
After this, you should have fully functional CrowPi laptop that you can do everything
you want to with it!
WiFi
Ethernet cable
