The EWS RFM23BP Breakout Board offers users a convenient way to get up and running with the RFM23BP long range RF module. The board offers a full pinout (0.100" spacing) of the RFM23BP module and is designed for easy plug-in on a standard breadboard. Or, use the board in conjunction with our ATMEGA1284P Development Board by interfacing through the easy SPI Header instead. The board even ships with a wire antenna installed!

HopeRF's RFM23BP wireless ISM transceiver is a highly integrated, low cost, long range module available here in the 433MHz and 915MHz frequencies. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.

The RFM23BP digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling for increased flexibility and performance. The direct digital transmit modulation and automatic PA power ramping ensure precise transmit modulation and reduced spectral spreading ensuring compliance with global regulations including FCC, ETSI.
