Glass2 Unit: Sleek Transparent OLED for Smart Interfaces The Glass2 Unit is a 1.51-inch transparent OLED display module powered by the SSD1309 driver. It supports I2C communication with a default address of 0x3C, and includes a solder pad for easy switching to 0x3D — perfect for multi-display setups! 🔄 🏠 Designed for Smart Home & Control Devices Whether you're building a home automation interface, a status indicator, or a custom UI, the Glass2 Unit is ready to shine. Its transparent design and compact form make it ideal for embedding into a wide range of smart products. 💡 📐 Display Specs 🧊 Glass area: 42 × 27.16 mm 🖥️ Display area: 35.5 × 18 mm 🖼️ Resolution: 128 × 64 pixels 🌈 Brightness: 256-level control for crisp visuals in any lighting Enjoy sharp, detailed images with optimized contrast and brightness — even in challenging environments. 🌞🌙 🔗 M5Stack Ecosystem Compatible Fully compatible with the M5Stack development platform, the Glass2 Unit lets you: 🎮 Build mini games 🧑🎨 Design custom info displays 🔌 Connect with other M5 modules ⚡ Performance Boost: No STM32 MCU Unlike the original Glass Unit, the Glass2 Unit does not include an STM32 MCU, which means: 🚀 Faster refresh rates ⚡ Quicker content updates 🎞️ Smoother animations and input response You can even control two Glass2 Units simultaneously by adjusting the I2C address. For larger setups, pair it with the PaHUB2 Unit to manage multiple displays with ease. 🔧 Glass Unit Glass2 Unit 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 Features 128x56 transparent pixels (128x64 total pixels) Display area 35.5 x 18mm Glass area 42mm x 27.16mm 1-bit color depth I2C Addresses: 0x3D support for programming platforms: Arduino、UIFlow Featured Articles M5Stack Unit Glass vs. Unit Glass2: Transparent OLED Display Comparison Includes 1x Glass2 Unit 1x Grove Cable (20cm) Applications Embedded display DIY toys Specification Resources Parameters Screen 1.51-inch transparent OLED resolution 128*64 Display color blue Display area 35.05*18（mm） Panel size 42.04*27.16*1.25（mm） Perspective direction Full view Operating temperature 0-40°C Logic voltage 3.3V I2C address default:0x3C（You can switch the communication address to 0x3D with bonding pad） Product Size 53*42*6mm Package Size 136*92*13mm Product Weight 9.1g Package Weight 13.9g
