Glass 2 Unit with 1.51 Transparent OLED

The Glass 2 Unit is a transparent OLED display featuring a 1.51′ screen and an SSD1309 driver. It is equipped with an I2C communication interface, set to a default address of 0x3C, but also includes a built-in solder pad for address modification to 0x3D. It is useful for displaying information, indicating status, or serving as a user interface, seamlessly integrating into various home or control devices to allow user interaction.

The unit has a glass area measuring 42 x 27.16mm, with a display area of 35.5 x 18mm, and offers a resolution of 128 x 64 pixels. It has a 256-level brightness control, providing rich detail and sharp imagery, and is adaptable to various lighting conditions for clear, readable displays.

The Glass 2 is compatible with the M5Stack development platform and its extensive product ecosystem, offering users a canvas for creativity and the development of diverse applications and functions. This ranges from crafting small games and personalised display interfaces to integrating with other M5Stack devices.

Revision History

• In comparison to its predecessor, the Glass Unit, the Glass 2 Unit omits an STM32 MCU. This exclusion means that by altering the I2C address via the onboard solder pad, it can control two Glass 2 Units at once. For projects requiring simultaneous control of multiple Glass Units, the PaHUB2 Unit is required. The absence of the STM32 MCU in the Glass 2 Unit enhances refresh efficiency, leading to quicker updates and responses to input, as well as smoother imagery and animation displays.
