The T-LoRa Pager from LILYGO is a compact IoT development board designed for applications such as asset tracking, remote sensing, and portable communication. It is powered by the ESP32-S3 microcontroller and comes with 16MB flash and 8MB PSRAM. Key hardware features include an RTC circuit, GPIO expansion headers, a battery management system, an audio codec, and a MicroSD card slot for additional storage.

For wireless communication, the board integrates the SX1262 LoRa transceiver, supporting sub-GHz frequencies including 433MHz, 868MHz, 915MHz, and 920MHz. A variant equipped with the LR1121 chip adds support for 2.4GHz LoRa in addition to sub-GHz bands. The board also includes NFC functionality for short-range communication.

Positioning is handled by the u-blox MIA-M10Q GNSS module, capable of concurrently tracking signals from up to four satellite constellations. An onboard IMU provides motion sensing features, enabling orientation and movement detection. These integrated functions make the T-LoRa Pager suitable for low-power, location-aware IoT projects.
