Waveshare ESP32-S3 LoRa Development Board With LR1121 3rd-Gen RF Chip LF Version

Equipped with the Xtensa 32-bit LX7 dual-core processor, with a main frequency up to 240MHz, delivering robust performance; supports

1. 4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), meeting diverse wireless connectivity needs. Built-in 512KB SRAM, 384KB ROM, stacked 4MB Flash, and 2MB PSRAM, offering abundant resources. Adopts stamp hole design for enhanced integration, facilitating independent baseboard design. Rich peripheral interfaces including 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, and 2 × ADC. Utilizes LR1121, the third-generation low-power LoRa transceiver from Semtechs LR11xx series. Supports Sub-GHz (150MHz to 960MHz), S-band (2.0GHz to
2. 1GHz), and
3. 4GHz ISM frequency bands. Connects to cloud platforms via LoRa or LoRaWAN protocols through gateways to build low-power wide-area networks. Supports LoRa, (G)FSK, and LR-FHSS modulation, compatible with SX126X/SX127X frequency bands for seamless product upgrades. Integrated AES-128 encryption engine for enhanced data security; onboard TCXO crystal ensures frequency stability under high/low-temperature conditions. Suitable for IoT applications including industrial telemetry, smart homes, environmental monitoring, and remote data acquisition. Includes C language sample programs and user manuals for streamlined development and rapid deployment. Operating frequency bands: LF: 410MHz to 510MHz; HF: 850MHz to 930MHz
