This is a decription on how to make a microphone module for the JOP Board

The objective with this article is to descibe how to make a simple analog to digital converter using the Sigma Delta converter model: Sigma-Delta ADC Tutorial

Following components are needed to make the hardware part of the analog to digital converter:

The circuit diagram[edit | edit source]

Solder it all together and attach it to your JOP board, then you should end up with a result that looks like this.

Audio in and out with Baseio[edit | edit source]

Connection of external components for a simple sigma-delta ADC and PWM DAC to the baseio board.
