Boardoza RFM90CW ESP32-S3 868 MHz LoRa Gateway Evaluation Board

Boardoza Gateway is a compact LoRa gateway board based on the ESP32-S3-Mini microcontroller. It manages system control, data processing, and communication while interfacing with an 868 MHz LoRa transceiver for long-range wireless connectivity. Designed to act as a gateway, the board receives data from remote LoRa nodes and forwards it through standard digital interfaces. SPI, I2C, and UART connections provide flexible integration with external modules, sensors, and host systems, making it suitable for IoT gateway, data aggregation, and telemetry applications.
