Open-Source ESP32 Walkie-Talkies Send Audio Without Wi-Fi

A DIY walkie-talkie built on the ESP32 microcontroller can transmit audio between devices without relying on Wi-Fi networks or internet access. The open-source project lets hobbyists build their own off-grid voice communicators using low-cost hardware. It is drawing attention from makers interested in independent communication tools that work where cellular and internet coverage fail.

Why now: Makers and privacy-minded users are drawn to cheap, open-source communication tools that work off-grid
