LILYGO T-Watch S3 Plus

T-Display K230

Introduction

The T-Watch S3 Plus version builds upon the T-Watch S3 by adding GPS functionality. Like the T-Watch S3, it is a multifunctional smart wearable device that integrates high-performance hardware and wireless communication technology, making it suitable for sports health monitoring, remote interaction, and audio applications.

Its core specifications include a 1.54-inch 240x240 HD LCD display, a BMA423 motion sensor, and a capacitive touch module for precise motion tracking and responsive touch operations. It also features a Max98357A audio amplifier and a PDM microphone, enabling high-quality audio output and voice command input.

Currently, the T-Watch S3 Plus is available in two versions: 1262 and 1280. It incorporates an RFC clock module, facilitating long-range, low-power wireless communication, making it ideal for IoT and industrial sensing applications.

With its compact design and integration of motion tracking, voice interaction, and remote communication, the T-Watch S3 Plus is well-suited for diverse applications such as outdoor adventures, health monitoring, and smart home control, combining both technological sophistication and practicality.
