LILYGO TTGO T-Lora Pager ESP32-S3 868mhz IPS LCD

The LilyGO T-LoRa Pager K257 is an innovative handheld device based on the ESP32-S3, integrating modern IoT technologies in a compact housing. With LoRa radio (SX1262), GNSS positioning (u-blox MIA-M10Q), NFC functionality (ST25R3916) and a bright 2.33-inch IPS display, the pager offers a versatile platform for wireless communication, mesh networks, and development projects. The integrated QWERTY keyboard and a rotary encoder facilitate operation and navigation. Thanks to the powerful ESP32-S3 hardware, with 16 MB Flash and 8 MB PSRAM, applications for messaging, IoT prototyping, edge AI, or sensor fusion can be realized. The built-in IMU sensor (BHI260AP) with AI support, haptic driver, audio codec with microphone and speaker, as well as the optional 3.5 mm audio jack, make the T-LoRa Pager a true all-in-one device. Programming, data transfer, and battery charging are performed via the USB-C interface. With support for Arduino IDE, ESP-IDF, and VS Code, the device can be used in numerous projects.
