Dear customer,

thank you for purchasing our product.

Please nd our instrucons below.

1. Systeminstallation

There are only a few steps for the rst installaon.

Please note that the Talking Pi set is only compable to the Raspberry Pi 3.

Older Raspberry Pis are not supported.

First, plug the Talking-Pi extensionboard on to the GPIO-Header of your Raspberry Pi so that both boards

are placed over each other.

The Talking-Pi set is fully compable to the Google AIY Project so we recommend to use the Voice Kit SD

image. You can download the image on the AIY project page.

Download the image and write it with a compable program (e.g. Etcher) to your SD-card.

You can insert the card to your Raspberry Pi aerwards.

You can now connect the supplied microphone-module to the Talking-Pi extensionboard.

The Talking-Pi system is now ready.

To acvate the Google Assistant SDK, and of course the voice control, you should follow the instrucons

on the AIY project page.

2. Installaon and acvang addional libraries

To be able to use all features of the Talking-Pi board you need to install and acvate addional modules

and libraries.

Follow the next steps to acvate all modules and be able to use all of the features.

Please remember to restart your Raspberry Pi aer you installed/acvated the modules.

2.1 Overview

Dierent modules are necessary for dierent features.

If you only need a few features or if you don‘t want to acvate all features, you can of course only

acvate the needed modules.

Note the overview below to see which modules are necessary for the dierent features.

2.2 I2C

The I2C funcons are already installed.

You just need to acvate them.

Open up a terminal window and enter the Raspberry conguraon menu with the following command:

Enter the Interfacing Opons menu.

And acvate the I2C opon by conrming the opening windows with Yes.

Now leave the conguraon menu and restart your Raspberry Pi.

Talking-Pi

sudo raspi-config

sudo reboot

2.3 Servo-Motor Extension

A special library is needed to use the servo-module.

This library is based on the Adafruit_PCA9685 Python-library but is specially adjusted to our board.

We recommend to use our own, adjusted, libary.

You can download the adjusted library here.

Copy the extracted library to your Raspberry Pi and navigate with a terminal into this folder.

Install the library with the following command;

2.4 wiringPi

The wiringPi libary is necessary to be able to connect addional modules (e.g. the 433 radio module).

Execute the following commands to install this library:

Talking-Pi

sudo python setup.py install

sudo apt-get install git git-core

git clone git://git.drogon.net/wiringPi

cd wiringPi

./build

2.5 433Utils

To use the radio modules, another library is necessary.

You can use the 433Uls library by ninjablocks.

This library was published under the MIT license and allows you to easily use the radio modules.

Talking-Pi

git clone https://github.com/ninjablocks/433Utils.git --recursive

cd 433Utils/RPi_utils

make all

3. Connecng a speaker

The Talking-Pi module is equipped with a preinstalled speaker-connector.

This one is suited for a speaker with a power of 3 Wa.

To connect a speaker, loosen the marked scews of the screw terminal.

Now connect the red speaker cable to the le opening (marked with a +) and the black speaker cable to

the right opening (marked with a -) and ghten the upper screws.

4. Using the 433 MHz radio modules

4.1 Connecng the modules

You can also connect sender and receivers of 433 MHz radio modules to the Talking-Pi board to control

radio devices.

Just plug the modules into the marked connecons (433 TXD: 3-Pin Sender, 433 RXD: 4-Pin Receiver).

The modules should (note the marked arrows) direct away from each other.

Warning! Please note that you can not use the Driver1 and Driver2 connecons and the 433MHz

modules at the same me.

The sender is connected to the GPIO port 17 and the receiver to the GPIO port 27.

Normally no addional conguraon is needed here.
