Amazing PiTeleCow A Compact Portable VoIP Phone

TapTechNews May 21st, there are many amazing Raspberry Pi projects on the internet, and the PiTeleCow project introduced in this article uses the Raspberry Pi Pico W to create an ultra-compact portable VoIP phone.

The PiTeleCow project, created by Derek Woodroffe, is a small and portable internet phone. However, it should be noted that it cannot be taken outdoors or used in the absence of a network. This phone can only operate in a Wi-Fi environment.

In addition to the Pi Pico W, the PiTeleCow device also uses an SD card, a built-in battery, a microphone, a speaker, a 15-key keyboard, and a micro OLED display.

The PiTeleCow device still needs to be improved at present. For example, the audio in the note list is often unstable, and once a call is initialized, it cannot be cancelled.
