AD9850 DDS Signal Generator Module

Signal generators / Function generators are super handy from RF to embedded logic, but they are usually not very cheap.

Good news: with this AD9850 DDS Module, you can create your own flexible, functional, and user-friendly Arduino frequency generator with some assembly!

With an LED display, rotary potentiometer, and an Arduino you can make an easy-to-use, standalone signal generator. (Don't forget to purchase a CP2102 USB to TTL Serial Converter if you don't already have one at home)

You can also choose to combine it only with an Arduino Uno on a breadboard.

A completely different route is to use this module to make your own Software Defined Radio (SDR).

In short, a great module to get started with!
