LILYGO T-Glass is an ESP32-S3-powered smart glasses development platform with a smart Bosch IMU, an integrated microphone, a touch button, and a 1.1-inch full-color prism display with 126 x 126 resolution. The features and specifications make this device similar to a Google Glass 2 or Google Glass Enterprise Edition v2 but with a developer-friendly codebase and much room for tinkering.
In our previous post, we also wrote about Pivothead SMART glasses and Qualcomm Snapdragon XR1 AR smart viewer feel free to check those out if you are looking for similar but more powerful products than this one.

The display used in this T-Glass is a JD9613 full-color LTPS AMOLED display with 294 x 126 pixels of resolution but the display area is only 126 x 126 pixels due to the prism used in the module.
The BHI260AP is an always-on type of self-learning AI smart sensor with a 6-axis IMU, a 32-bit MCU which gets complemented by a wide variety of software functionalities making it ideal for applications like fitness tracking, pedestrian positioning, machine learning analytics, orientation estimation, and more. It also supports sophisticated machine learning analytics, making it easy to capture precise motion and interpret data.
On LILYGO’s GitHub repository, you can find many examples for the device including Glass6DoF for motion tracking, GlassBatteryVoltage battery level monitor, and many more examples like a real-time clock, touch buttons, and voice activity detection to help users quickly start developing with the device.
The LILYGO T-Glass is currently available on Amazon for $48. It’s also listed on AliExpress and the LILYGO store, but it’s out of stock in both locations.

It’s been sold out for a while now…
It’s available on Amazon, but it’s been out of stock on Aliexpress and the LILYGO website almost since launch.
I think the form factor of the tiny corner display proved to be junk (causing eye strain), but this one at least appears to have it centered.
Am I getting this right, no camera? That knocks off a lot of use cases.
Google Glass was way ahead of it’s time
More like this thing is behind the times.
If the other IO pins are accessible, I definitely want to buy a couple of these. A 126×126 display is a little limiting, but manageable.
