A powerful LoRa expansion board based on the STM32WL55CCU6 MCU, designed to provide long-range wireless communication for embedded systems. Supporting I2C, UART, and SPI interfaces, this board can easily integrate with other MCUs in larger projects. Ideal for IoT applications requiring low-power, long-range data transmission.
A 2-layer PCB design of the ESP32 Dev Kit V1 (30-pin), created using KiCad 9.0. Includes complete schematics, layout, and BOM.
