RFM68W
RFM68W is Low Cost ISM Transmitter Module manufactured by HOPERF.
Features
GENERAL DESCRIPTION
The RFM68W is an ultra-low-cost, FSK or OOK transmitter module suitable for operation in the 315, 433, 868 and 915 MHz licence free ISM bands., the RFM68W may be used without the requirement for configuration via an MCU. However, in conjunction with a microcontroller, the munication link parameters may be re-configured. Including, output power, modulation format and operating channel. The RFM68W offers integrated radio performance with cost efficiency and is suited for operation in North America FCC part 15.231, FCC part 15.247 DTS and FHSS modes,15.249, and Europe EN 300 220. In order to better use RFM68W modules, this specification also involves a large number of the parameters and functions of its core chip RF68's,including those IC pins which are not leaded out. All of these can help customers gain a better understanding of the performance of RFM68W modules, and enhance the application skills.
