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!
