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.
This dual-MCU repository features a heterogeneous architecture pairing an ESP32-P4 application processor with an ESP32-C5 Wi-Fi 6/BLE hub. Linked over a high-bandwidth 4-bit parallel SDIO interconnect, this design decouples heavy multimedia task execution from the networking stack to completely eliminate application interrupt starvation.
