The RFM68W-433 is a very low-cost short-range 433MHz ISM-band transmitter module.The RFM68W may be used without the requirement for configuration via an MCU. However, when connected to an MCU, the communication link parameters may be re-configured, including output power, modulation format and operating channel.
Carrier Frequency range: 380 to 450MHz. RF Output Power: +10dBm or 0dBm. Modulation: FSK or OOK. Data rate: Up to 100kbps. Low BOM Fully Integrated Tx. Fractional-N PLL with 1.5 kHz typical step. Frequency agility for FHSS modulation. Single serial I/O pin. Power supply: +1.8 to +3.7Vdc. Operating temperature range: -20 to +70°C. Dimensions: 14.5 x 15 x 1.7mm. FCC Part 15.247 DTS Mode compliant. Applications: Remote Keyless Entry (RKE), Remote Control / Security Systems, Local communication for the Internet-of-Things (IoT)
