Jun 29, 2023

LILYGO T-TWR is an ESP32-S3 development board fitted with an SA868 Walkie-Talkie module and a UHF or VHF antenna, a speaker, a microphone, a small 0.96-inch OLED, and a 18650 battery holder, plus some I/Os for expansion.

Equipped with an ESP32-S3-WROOM-1-16NR8 module, the T-TWR offers WiFi 4 and Bluetooth 5.0 connectivity, a dual-core processor with 16MB flash and 8MB PSRAM, and enables users to design their own Walkie-Talkie, while its expansion capabilities allow the control of devices.

LILYGO T-TWR specifications:

The T-TWR ESP32-S3 Walkie-Talkie board can be programmed with the Arduino IDE or PlatformIO, and LILYGO provides documentation as well as schematics (PDF), datasheets, and sample code on GitHub. Two samples are provided one using the board as an actual Walkie-Taklie, and the “at_debug” demo to control the board through AT commands over a serial interface.

LILYGO is selling the T-TWR board for $41.98 to $45.98 on Aliexpress including shipping, but not taxes (VAT). It provides an alternative to the SOCORAD32 ESP32 walkie-talkie board that is currently offered on Crowd Supply for $80.
