This document introduces the basic features and functions of the RFC30F wireless module from NewMsgTech. The module uses the nRF905 chip and operates on the 433, 868, and 915MHz channels. It can communicate with any MCU through the SPI interface. The module features low power consumption, long-distance communication, and reliable data transmission, making it suitable for industrial data acquisition, wireless alarm, and security systems.
This manual describes the NewMsgTech RFC30F wireless module, a low‑power ISM‑band transceiver supporting 433 MHz, 868 MHz and 915 MHz frequencies. It outlines key features such as ShockBurst™ operation, programmable output power up to 20 dBm, and typical current consumption of 12.5 mA.
The document includes the pinout diagram, voltage requirements (3.3 V supply), and detailed programming examples for configuring TX/RX modes, SPI communication, and using the ShockBurst™ protocol. It also provides electrical characteristics and troubleshooting tips.
