Description
Development board designed for IoT and wireless communication systems, based on the ESP32-S3 microcontroller with a dual-core Xtensa LX7 processor operating at up to 240 MHz. The integrated LR1121 RF chip enables communication in Sub-GHz and 2.4 GHz bands, supporting LoRa, (G)FSK and LR-FHSS modulation schemes.
HF version operates in the 850–930 MHz and 2.4 GHz frequency ranges, allowing deployment in long-range communication systems compliant with regional radio regulations. LoRaWAN support enables integration with LPWAN networks and cloud communication via gateways.
The module provides multiple communication interfaces including SPI, I2C, UART and I2S, allowing connection of external peripherals. Castellated edge pads enable direct soldering onto carrier boards, simplifying integration into target hardware designs.
The TCXO oscillator ensures stable frequency operation across a wide temperature range, while built-in AES-128 encryption enhances data transmission security. The module is suitable for telemetry systems, environmental monitoring, smart infrastructure and remote data acquisition applications.
