Omschrijving
Raspberry Pi 4, 2 GB RAM
De Raspberry Pi 4 zet een nieuwe mijlpaal in processorsnelheid en prestaties van single-board computers. Raspberry Pi 4 is 3x sneller dan zijn 3 B+ voorganger en biedt 4x snellere multimedia prestaties (vergelijkbaar met de desktop prestaties van een entry-level x86-gebaseerde PC).
Kenmerken
- Krachtige 64-bit quad-core processor
- Ondersteuning voor twee schermen met resoluties tot 4K via een paar micro-HDMI-poorten
- Hardware videodecodering tot 4Kp60
- 2 GB RAM
- Dual-band 2,4/5 GHz draadloze LAN
- Bluetooth 5.0
- Gigabit Ethernet
- USB 3.0
- PoE-mogelijkheid (via een aparte PoE HAT add-on)

Raspberry Pi Full Stack (E-book)
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.
