Description
ESP32 Audio Board For Walkie-Talkie v2
I'm building a Walkie-Talkie based around the ESP32. This PCB wires together all the required modules and adds an independent supply to the microphone boards so you minimise noise when WiFi is being used.
You can use either an INMP-441 board or my microphone board (available from Tindie: https://www.tindie.com/products/21519/)
I made up this PCB as the wires to connect all the modules were getting quite untidy and I wanted to build in the power supply filtering.
Note - this is just a bare PCB - you will need to purchase the components yourself.

This is a very basic audio board that wires together with an ESP32 dev module with an I2S amplifier and I2S microphone boards.
