The Elecbee LILYGO T-Wrist E-Paper is designed to solve the power-drain challenges of traditional smart wearables. By combining a 1.54-inch electronic paper display with a high-efficiency ESP32 MCU, this board allows developers to create "always-on" devices that last significantly longer on a single charge. It is an ideal platform for smartwatches, GPS trackers, and portable IoT notification modules that require readability in direct sunlight without consuming continuous power.
This development board features integrated GNSS technology through the LG77 receiver, ensuring reliable location data across multiple satellite constellations. The E-ink screen supports fast partial refreshes in just 0.3 seconds, maintaining crisp 200x200 resolution. Standard hardware features include:
The T-Wrist package is engineered for durability and versatility, featuring a gold immersion process on the PCB for enhanced conductivity. The inclusion of a low-noise vibration motor adds a physical feedback dimension for user alerts. Each kit comes ready to program with a Type-C USB cable and a dedicated GPS antenna to maximize signal reception for the LG77 GNSS module. This module supports comprehensive development environments including Arduino and MicroPython.
