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.
