Get a compact and powerful platform for autonomous communications and geolocation systems. The TTGO T-Beam V1.1 module combines an ESP32 microcontroller, a long-range LoRa transceiver SX1262, a NEO-6M GPS receiver and a 18650 battery holder. A built-in OLED display displays coordinates and operating status. This is an ideal solution for creating Meshtastic decentralized mesh networks, portable trackers and field IoT devices.

• Long-distance LoRa communication. The SX1262 transceiver provides data transmission over kilometers with ultra-low power consumption.

• Built-in GPS NEO-6M. Precise positioning for tracking and geofencing, work in any field conditions.

• Autonomous power supply. 18650 battery holder on the back of the board for long battery life.

• Flexible interfaces. Supports Wi‑Fi 2.4 GHz, Bluetooth 4.2, SPI, I2C, UART for connecting sensors and peripherals.

• Ready for Meshtastic. Fully compatible with the popular protocol for creating secure Mesh networks.

Operating principle and opportunities for the developer

The TTGO T-Beam V1.1 module is based on an ESP32 microcontroller with a dual-core processor, 4 MB Flash and 8 MB PSRAM. Power management is carried out by the AXP192 chip, which ensures charging and stable operation from an 18650 battery. The SX1262 LoRa module operates in the 433/868/915 MHz bands with output power up to +20 dBm and reception sensitivity up to -139 dBm. GPS NEO-6M uses a ceramic antenna and has a backup battery for quick start.

The Arduino IDE and PlatformIO are available for development with extensive libraries and examples on GitHub.

The LILYGO TTGO T-Beam V1.1 module will be an ideal basis for creating Meshtastic field nodes, autonomous trackers for drones and vehicles, remote object monitoring systems, as well as LoRa repeaters and environmental sensors.
