The Glass2 Unit is a 1.51-inch transparent OLED display module that utilizes the SSD1309 driver solution. This unit supports the I2C communication interface, with a default address of 0x3C. It is equipped with a solder pad that facilitates the modification of the communication address to 0x3D.
The Glass2 Unit is designed for integration into home products and control devices, offering functionality for information display, status indication, and user interfaces. Its versatile application enables it to be embedded in a variety of home products or control devices, thereby enhancing user interaction.
The Glass2 Unit features a glass area measuring 42x27.16mm, with a display area of 35.5x18mm and a resolution of 128x64 pixels. It offers 256-level brightness control, which enhances the visibility of display content, providing detailed and sharp images. The brightness and contrast are optimized for clear display effects in various lighting conditions.
The Glass2 Unit is compatible with M5Stack's development platform and its product ecosystem, enabling users to develop a range of applications and functions. This includes creating small games, designing personalized information display interfaces, and connecting with other M5Stack devices.
The Glass2 Unit differs from the Glass Unit in that it does not contain an STM32 MCU. By adjusting the I2C address via the onboard solder pad, it is capable of controlling two Glass2 Units simultaneously. For projects requiring the simultaneous control of multiple Glass Units, the PaHUB2 Unit must be used for connections. The absence of the STM32 MCU in the Glass2 Unit enhances refresh efficiency, which allows for quicker content updates, improved responsiveness to input signals, and more fluid displays of images or animations.

| Built-in STM32 control scheme, can simultaneously control dozens or even more via an I2C bus Glass Unit . | The I2C address can be changed through the onboard pad, so only two Glass2 units can be controlled simultaneously through the I2C bus. To control multiple Glass2 units in the project, please use PaHUB2 |
