LilyGo T-Deck Pro 868MHz LoRa Module with 2.8 Inch E-Ink Display

The LilyGo T-Deck ESP32-S3 is a powerful all-in-one module with an integrated 2.8-inch E-Ink display and built-in 868MHz LoRa technology. It is based on the ESP32-S3R8, a dual-core microcontroller with Wi-Fi and Bluetooth LE. The device is ideal for mobile projects requiring low-power display and wireless communication. The built-in E-Ink screen is especially energy-efficient and provides excellent readability in daylight. In addition to the display, the T-Deck features a QWERTY keyboard, a microphone, speakers, and a 3.5 mm audio jack. Power and flashing of new software are provided via USB-C. The internal battery connector with charging circuit allows for mobile use without an external power source. A MicroSD card slot, a programmable RGB-LED, and various GPIO connections expand functionality. The housing is fully pre-assembled and robustly designed. Thanks to the open software architecture, the module is ideally suited for DIY applications, terminal projects, or IoT controls. The manufacturer provides comprehensive documentation and sample code.
