Overview
The LILYGO T-Beam is one of the most feature-complete LoRa development boards available, combining an Espressif ESP32 dual-core processor with a Semtech SX1276 (868/915/923 MHz) or SX1278 (433 MHz) LoRa transceiver, a u-blox NEO-6M GPS module, and a 0.96-inch SSD1306 OLED display on a single board. An 18650 battery holder and onboard charging circuit make it fully self-contained for portable field deployments.
The T-Beam is the reference hardware for Meshtastic — the open-source LoRa mesh networking firmware — and also runs SoftRF, Paxcounter, and custom Arduino/MicroPython projects. The NEO-6M GPS provides reliable satellite positioning with 50-channel receive sensitivity of -161 dBm, enabling real-time tracking applications. With 8MB PSRAM and 4MB flash alongside WiFi and Bluetooth 4.2, the ESP32 handles concurrent LoRa packet routing, GPS parsing, and display updates with ease.
Three onboard buttons (Power, IO38, Reset), the CH9102 USB-UART bridge, and standard 0.1-inch headers provide convenient programming and expansion. Available in 433 MHz (SX1278) and 868/915/923 MHz (SX1276) variants to match regional LoRa frequency allocations worldwide.
