DIY Walkie-Talkie With Generic 433MHz RF Modules

Introduction: DIY Walkie-Talkie With Generic 433MHz RF Modules

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how to use generic 433MHz RF modules from Ebay in order to create a functional Walkie-Talkie. That means we will compare different RF Modules, learn a bit about a class d amplifier and finally build the Walkie-Talkie. It can be powered by a normal powerbank for around 130 hours and features a range of around 15m. Let's get started!

Step 1: Watch the Video!

Make sure to watch the video! It gives you all the information you need to create your own Walkie-Talkie. During the next steps though I will present you some additional information.

Step 2: Order Your Components!
