T-Beam get it now

Overview

LILYGO T-Beam is a feature-rich ESP32-based development board combining LoRa long-range wireless communication, GPS positioning, and battery management in a single compact form factor. Based on the ESP32 dual-core LX6 processor with Wi-Fi and Bluetooth 4.2, it integrates an SX1276/SX1278 LoRa module (433/868/915 MHz), a GPS module (NEO-6M or compatible), a 0.96-inch SSD1306 OLED display (128×64), and an AXP192 PMU with 18650 battery holder. Widely used for Meshtastic mesh networking, APRS tracking, LoRaWAN nodes, and portable IoT applications.
