RFM50 module series’ design is based on the high performance RF50 SoC chip, It include a CIP-51 core‘ MCU and 100mW transceiver. It operate at 433/470/868/915 MHz ISM band, comply with FCC, ETSI regulation.
SR150U is a high-power wireless voice intercom and long-range data transmission module. Based on automatic power tracking technology, it maintains consistent transmission power across the entire frequency band.
The SR150U is the industry's first compact, high-power wireless voice intercom and long-range data transmission module. Based on automatic power tracking technology, it maintains consistent transmission power across the entire frequency band.
The module integrates a high-performance RF transceiver chip, microcontroller, and RF power amplifier. External controllers can set module parameters and control transmission/reception through standard UART (TTL level) communication. The module only requires an external antenna, microphone, and audio amplifier to form a complete intercom or data radio station. Module parameters can be saved after power off, and no external microcontroller is needed for simple applications.
