Summary
- Hackster.io user Jonathan R has created a video walkie-talkie using two inexpensive ESP32 processors, which typically cost under $10.
- The ESP32 is generally used in more complex projects because of its powerful core and built-in wireless networking capabilities.
- For the video walkie-talkie, one ESP32 is used in a camera module, and the other in a screen module.
- Audio uses ESP-NOW, and video uses WiFi.
- There is a small amount of lag, but for such a cheap device this is negligible.
