LILYGO T-Beam Supreme

Overview

The LILYGO T-Beam Supreme is the flagship member of the T-Beam family, offering extensive frequency band support and GPS module options in a single platform. It supports LoRa communication across 433 MHz, 144-148 MHz (amateur radio), 868 MHz (Europe), 915 MHz (Americas), and 920 MHz (Asia-Pacific) bands, enabling global deployment flexibility.

Two GPS module choices are offered: the L76K multi-constellation GNSS (cost-effective option supporting GPS, BDS, GLONASS) and the u-blox module (higher accuracy, faster acquisition). The LoRa transceiver provides +22dBm transmit power for maximum range in LoRaWAN and peer-to-peer communication scenarios.

Multiple firmware options are available at purchase: LILYGO Factory Firmware for general-purpose development, or SoftRF Firmware for digital aircraft tracking and amateur radio applications. The board supports 18650 battery operation for field deployments. The T-Beam Supreme is widely used in Helium Network mapping, Meshtastic mesh networking, APRS tracking, and LoRaWAN node development.

Firmware Compatibility

• SoftRF: Pre-flashed variant available for aircraft transponder and ADS-B data reception.
• Meshtastic: Compatible for off-grid LoRa mesh networking.
• Arduino: Supported via Espressif Arduino core with LoRa, GPS, and power management libraries.
• ESP-IDF: Native Espressif development framework.
• Helium Mapper: Compatible with Helium Network coverage mapping.

Flashing Guide

1. Connect the T-Beam Supreme via USB-C cable.
2. Enter bootloader mode: hold BOOT, press RESET, release RESET, then release BOOT.
3. In Arduino IDE, select ESP32 Dev Module with the appropriate flash size.
4. Install required libraries for your use case (LMIC/RadioLib for LoRa, TinyGPS++ for GPS).
5. Set the correct frequency band in your firmware configuration.
6. Upload the firmware, press RESET to start.
7. Attach the appropriate antennas (LoRa and GPS) before powering on and transmitting.
8. Insert an 18650 battery for portable operation.
