LILYGO T-Glass IS A Google Glass Like Smart Glass Powered by an ESP32-S3


ilyT-Glass is an ESP32-S3-powered smart glasses with a smart Bosch AI IMU. The Bosch IMU is an AI smart sensor that integrates a 6-axis IMU, a 32-bit customizable programmable microcontroller, and various software functionalities. With these functionalities, this can be used in applications like navigation, machine learning analytics, and orientation estimation. All the main features of this board are very similar to the Google Glass 2 but with open-source code and a lot of room for development.

The display used in this glass is a JD9613 full-color LTPS AMOLED display with 294 x 126 pixels of resolution, but the actual display area is less than the full display spec of the module as there is a prism attached in the form of the glass to give it a 3D look.

Previously we have written about Voxos smart glasses and other smart glasses feel free to check that out if you are interested in the topic.

Looking at the BHI260AP sensor we find that it is an always-on type self-learning sensor with a 6-axis IMU, and a 32-bit MCU with example software and ML models making it ideal for remote monitoring applications. It also supports sophisticated machine learning analytics, which makes it easy to capture precise motion.
