Description
Raspberry Pi 4, 2 Go de RAM
Le Raspberry Pi 4 se démarque de tous les autres ordinateurs mono-carte en matière de performances matérielles. Il est trois fois plus rapide que le modèle 3B+ précédent, et il offre des vitesses d’affichage quatre fois plus rapides que celles d’un PC à microprocesseur x86 d’entrée de gamme.
Caractéristiques
- Processeur quadricœur 64 bits à haute performance
- Prise en charge de deux écrans 4K reliés aux ports micro-HDMI
- Décodage vidéo matériel jusqu’à H.265 (4K @60 i/s)
- 2 Go de RAM
- Wi-Fi bibande 2,4/5 GHz
- Bluetooth 5.0
- Gigabit Ethernet
- USB 3.0
- Capacité PoE (par carte d’extension HAT PoE)

Raspberry Pi Full Stack (livre numérique)
This book will take you on a whirlwind tour of full-stack web application development using Raspberry Pi. You will learn how to build an application from the ground up.
You will gain experience and know-how of technologies including:
- The Linux operating system and command line.
- The Python programming language.
- The Raspberry Pi General Purpose Input Output pins (GPIOs).
- The Nginx web server.
- Flask Python web application microframework.
- JQuery and CSS for creating user interfaces.
- Dealing with time zones.
- Creating charts with Plotly and Google Charts.
- Data logging with Google Sheet.
- Developing applets with IFTTT.
- Securing your application with SSL.
- Receiving SMS notifications to your phone using Twilio.
This book will also teach you how to set up a remote wireless Arduino sensor node and collect data from it. Your Raspberry Pi web application will be able to process Arduino node data in the same way it processes data from its onboard sensor.
Raspberry Pi Full Stack will teach you many skills essential to building Web and Internet of Things applications.
The application you will build in this project is a platform that you can extend upon. This is just the start of what you can do with a Raspberry Pi and the software and hardware components that you will learn about.
This book is supported by the author via a dedicated discussion space.
