The T-Watch S3 by LILYGO, is a cool smartwatch that will catch the attention of folks interested in cost-effectiveness. Fueled by the advanced ESP32-S3 System-on-Chip (SoC), it boasts seamless Wi-Fi and even BLE connectivity. The avant-garde open-source device is outfitted with a 1.54” LCD screen, distinguished by its capacitive touch capabilities, and it comes with full compatibility with the Arduino platform.

In stark contrast to the ESP32-PICO-D4 microcontroller-based SQFMI Watchy, the fresh and innovative smartwatch from LILYGO shines a spotlight on the prowess of the ESP32-S3 SoC, an engineering marvel featuring attributes like the ESP32-S3 – a Dual-core Xtensa 32-bit LX7 processor — demonstrating the capability to reach speeds of up to 240MHz.

For seamless, uninterrupted connectivity, this ingenious smartwatch integrates the Semtech SX1262 low-power LoRa Transceiver, catering to frequencies spanning 433MHz, 868MHz, and 915MHz.

The T-Watch S3 boasts an expansive 1.54″ LCD screen, offering a crystal-clear resolution of 240 x 240 pixels, complemented by the incorporation of cutting-edge capacitive touch technology. Moreover, it seamlessly fuses a class D amplifier and a PDM microphone, enriching the user experience.

A feature of paramount significance within the T-Watch S3 is the inclusion of Texas Instruments’ DRV2605, an adaptable haptic control apparatus meticulously engineered to interface with both ERM and LRA actuators, ensuring a tactile experience like no other.

LILYGO guarantees unfaltering compatibility with an array of programming environments, including MicroPython, ESP-IDF, VS Code, and the Arduino IDE. To enrich the user experience, the company furnishes an extensive reservoir of documentation accessible through its GitHub repository and a dedicated wiki. For a comprehensive overview, we invite you to explore the illustrative demo video provided above.
