1. Producte acabatview

The LILYGO® T-LoRa Pager is a handheld ESP32-S3-based programmable IoT development device designed for compact, stylish, and powerful wireless applications. It features a foldable antenna design for excellent RF performance and portability.

This versatile device integrates a 2.33-inch 222×480 display, full QWERTY keyboard, AI-enabled IMU (BHI260AP), U-blox GPS (MIA-M10Q), and NFC/RFID with RTC. For audio, it includes the ES8311 chip supporting microphone, speaker, and headset. Developers can expand further with the 2×8 GPIO header, encoder with push button, and NRF24L01 module compatibility. Power management is handled by TI monitoring chips for stability and efficiency.

Out of the box, the T-LoRa Pager comes with a LILYGO-designed UI demo, enabling smooth interaction through the encoder and offering a foundation for custom development. With various mounting options and an included branded lanyard, it is ideal for wearable devices, GPS trackers, smart terminals, and portable IoT prototypes.

4.2 LoRa Communication

The T-LoRa Pager is equipped with an SX1262 LoRa module (or LR1121/CC1101 depending on version) for long-range, low-power wireless communication. The pre-loaded UI demo often includes a 'LoRa Chat' application for basic messaging.

4.3 GPS, NFC/RFID, and AI Sensor

Depending on the firmware loaded, you can utilize the integrated GPS for location tracking, NFC/RFID for short-range identification, and the AI-enabled IMU (BHI260AP) for motion sensing and AIoT applications.

4.4 Audio Functionality

The ES8311 audio codec supports microphone input, speaker output, and headset connectivity, enabling voice communication or audio alerts in your projects.

5. Manteniment

5.1 Càrrega

Recharge the device using a standard 5V, 500mA USB-C power adapter. Avoid using chargers with higher voltage or current ratings unless specified, as this may damage the device.

5.2 Actualitzacions de programari

Regularly check the LILYGO GitHub repository for firmware updates and new features. Follow the provided instructions on GitHub for flashing new firmware to your device.

5.3 Atenció física

  • Mantingueu el dispositiu sec i allunyat de temperatures extremes.
  • Eviteu deixar caure o sotmetre el dispositiu a forts impactes.
  • Clean the screen and keyboard with a soft, dry cloth.
  • Ensure antennas are folded when not in use or during transport to prevent damage.

6. Solució De Problemes

If you encounter issues with your T-LoRa Pager, consider the following:

  • El dispositiu no s'encén: Assegureu-vos que el dispositiu estigui completament carregat. Connecteu-lo a una font d'alimentació i torneu-ho a provar.
  • Connectivity Issues (LoRa/GPS): Check that antennas are properly deployed. Verify your firmware configuration for correct frequency bands and settings.
  • Software/Firmware Problems: If the device behaves unexpectedly, try reflashing the firmware from the official GitHub repository. Ensure you are using the correct version for your specific T-LoRa Pager model (e.g., SX1262 vs. LR1121).
  • Avaries generals: A soft reset (using the Reset button) can often resolve minor software glitches.
