🚀 LILYGO® T3 STM32WL55 LoRa Node is a compact yet powerful IoT development board designed for versatility, low power, and mesh networking. At its core is the high-performance STM32WL55CCU6 dual-core microcontroller (Arm® Cortex®-M4 + M0+), offering robust processing for complex LoRa mesh applications. 🧠
With integrated LoRa® radio (SX1262) supporting 433/868/915MHz bands and modulation types like (G)FSK, (G)MSK, BPSK, this board is fully MeshCore compatible and ideal for building multi-hop LoRa mesh networks. 🌐
Additional features include a crisp 0.96" OLED display (SSD1315 I2C), Grove connector, TF card slot, SWD debug interface, and flexible power options – making it a perfect choice for embedded systems, IoT prototyping, and low-power wireless projects. 🔋📡
