Description

Adafruit Learn Guide: https://learn.adafruit.com/esp-now-walkie-talkies

A Feather ESP32-S3 Reverse TFT runs Arduino code that uses the ESP-NOW wireless protocol to send and receive I2S audio packets, up to 10 seconds each. The w.FL antenna adds extra range to communicate at longer distances indoors or outdoors. The case design is inspired by toy walkie talkies that were ubiquitous in the early-1990s.
