Low-cost Smartwatch powered by ESP32 module

The T-Watch S3 from LILYGO is an open-source smartwatch built with the ESP32-S3 SoC, featuring Wi-Fi and BLE connectivity. Unlike the SQFMI Watchy, which uses the ESP32-PICO-D4 microcontroller, the T-Watch S3 incorporates the ESP32-S3 System-on-Chip. It includes a 1.54″ LCD display with capacitive touch technology, as well as Arduino support. The smartwatch also features the Semtech SX1262 LoRa Transceiver for connectivity and the DRV2605 haptic control device from Texas Instruments. The T-Watch S3 supports MicroPython, ESP-IDF, VS Code, and the Arduino IDE, with documentation available on their GitHub repository and wiki page. The smartwatch starts at $39.90 and is available for purchase from the official LILYGO online store or their AliExpress store.
