LilyGO T3 STM32WL55 LoRa Development Board w/ 0.96-Inch OLED

Description

The LilyGO T3 STM32 Development Board consolidates a powerful wireless microcontroller and a user interface into a single, compact platform. At its core is the STM32WL55, featuring a dual-core Arm Cortex-M4 and Cortex-M0+ architecture alongside a fully integrated Sub-1GHz radio supporting LoRa, (G)FSK, MSK, and BPSK modulations across 433, 868, and 915 MHz bands. This integration eliminates external transceiver ICs, streamlining design and reducing power consumption for long-range IoT deployments.

Engineered for field deployment, the board includes an onboard antenna and is built around a low-leakage power management system, enabling extended operation from small batteries. The integrated 128×64 pixel OLED provides immediate visual feedback for sensor readings, network status, or device configuration, accelerating prototyping and reducing system complexity. Its USB Type-C port delivers robust connectivity for both firmware flashing via ST-LINK/V2-1 and serial communication, while the exposed GPIO via pin headers allows for rapid sensor and actuator integration.
