Another Walkie Talkie

We created a two way radio transceiver that can operate on a number of channels around 462 MHz.

Key Components:

• ESP32

• PAM8403D Audio amplifier

• NRF24L Radio Transceiver

• 3.3V regulator

• Power and transmit switches

• Volume knob

• Indicator LEDs

• Dual Speakers

• Microphone

• USB port

The walkie talkie uses SPI communication on board and can have many frequencies programmed in.
