LilyGO T-Watch S3 ESP32-S3 LoRa 1.54" Touch display watch
Code: LA100116C



Product detailed description
The latest version of the open-source development kit for wearable electronics in the shape and size of a smartwatch. The T-Watch S3 is based on the powerful ESP32-S3 microcontroller with WiFi and Bluetooth BLE 5.0 support. The watch is also equipped with a LoRa SX1262 module, enabling long-distance communication with minimal power consumption.
The kit includes a 1.54" capacitive touch display, a BMA423 3-axis accelerometer, a real-time clock, a microphone, a MAX98357A audio amplifier, a DRV2605 haptic driver, and advanced AXP2101 power management. Power is provided by a Li-ion battery, and charging is done via a USB-C connector.
The watch is ideal for developers who want to experiment with LoRa and ESP32-S3 in wearable electronics. It is highly customisable and usable in many applications.
Programming is performed in the Arduino IDE, ESP-IDF, VS Code or MicroPython environments.
