We've made a Walkie-Talkie using the ESP32. Audio data is transmitted over either UDP broadcast or ESP-NOW. So the Walkie-Talkie will even work without a WiFi network! • The custom PCBs I've had made up were manufactured by PCBWay and as always they've done a really great job. You can order the boards directly from PCBWay here: https://www.pcbway.com/project/sharep... • And you can help support the channel by using my referral link: https://www.pcbway.com/setinvite.aspx... for other PCBs. • If you like ESP32 audio videos - I've got a complete set on this playlist: • ESP32 Audio • I'm using my own microphone board (available on Tindie: https://www.tindie.com/products/21519/) but the code will work equally well with any I2S microphone (e.g. the INMP441) and you can easily modify it to use the built-in ADC for analogue microphones. • For output, I'm using an I2S amplifier breakout board which I'm using the drive a 4ohm speaker. Once again, you can modify the code to use the built-in DAC for output which will let you use headphones or an analogue amplifier board. • As always, the code is on GitHub: https://github.com/atomic14/esp32-wal... • I've got a great series of videos on ESP32 Audio which are a great resource for anyone who wants to learn more about audio on the ESP32 which you can find here: • ESP32 Audio • For this project I've 3D printed a case - you can access the Fusion 360 project here: https://a360.co/2PXgAUS • You can access the PCB schematic here: https://easyeda.com/chris_9044/esp32-... • Thanks for watching - there are more videos coming - so don't forget to subscribe :) • Components: • TinyPico: https://amzn.to/3e525YR • Microphone: https://www.tindie.com/products/21519/ or https://amzn.to/3e2oIgy • Amplifier: https://amzn.to/3xC0yRF • Speakers: https://amzn.to/3xzRkp2 • ---- • Patreon: / atomic14 • ko-fi: https://ko-fi.com/atomic14
