Buy LILYGO TTGO Meshtastic T-Beam V1.1 module for long-distance LoRa projects and GPS tracking

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

5 main advantages

• Long-distance LoRa communication. The SX1262 transceiver delivers miles of data with ultra-low power consumption. Reception sensitivity reaches -139 dBm, which guarantees reliable reception even in difficult conditions.
• Accurate GPS positioning. Built-in GPS NEO-6M with ceramic antenna and battery backup provides fast and accurate coordinate determination for tracking and geofencing.
• Autonomous power supply. 18650 battery holder on the back of the board allows you to work without recharging. Power management is carried out by the AXP192 chip, which ensures charging and stable battery operation.
• Flexible interfaces. Supports Wi‑Fi 2.4 GHz, Bluetooth 4.2, SPI, I2C, UART for connecting sensors and peripherals. This makes it easy to integrate the module into any projects.
• Ready for Meshtastic. Fully compatible with the popular protocol for creating secure Mesh networks.

TTGO T-Beam V1.1 module is based on an ESP32 microcontroller with a dual-core processor, 4 MB Flash and 8 MB PSRAM. LoRa module SX1262 operates in the 433/868/915 MHz bands with output power up to +20 dBm. It enables long-distance and energy-efficient data transmission. GPS NEO-6M with ceramic antenna and battery backup ensures fast positioning.

Built-in OLED display displays coordinates, network status and other information. Arduino IDE and PlatformIO environments are available for development with extensive libraries and examples on GitHub.

Features of the T-Beam range

The T-Beam line includes several versions. V1.1 uses ESP32, LoRa SX1276 or SX1262 and GPS NEO-6M or NEO-M8N. Newer versions such as T-Beam Supreme use ESP32-S3 and SX1262. The V1.1 model remains a popular choice due to its optimal price/functionality ratio. It is ideal for Meshtastic projects, trackers and LoRa repeaters.
