Introduction

AI Translation

Ra-09H is a LoRa module designed for ultra-long-range spread spectrum communication. Its core chip, STM32WLE5CCU6, is a general-purpose LPWAN wireless communication SoC integrating an RF transceiver, modem, and 32-bit Arm Cortex-M4 MCU. The module supports LoRa modulation and legacy (G)FSK modulation for LPWAN applications; additionally, the transmitter supports BPSK and (G)MSK modulation, while the receiver supports (G)MSK modulation. The module delivers ultra-long-range, ultra-low-power communication for LPWAN applications.
