Product specifications
HopeRF's RFM43B are highly integrated, low cost,433/868/915MHZ wireless ISM transmitters module.
The RFM43B offers advanced radio features including adjustable power output levels of –8 to +13dBm.Power adjustments are made in 3dB steps.The RFM43B's high level of integration offers reduced BOM cost while implifying the overall system design. Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX FIFO, and automatic packet handling reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size. 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 regulations. An easy-to-use calculator is provided to quickly configure the radio settings,simplifying customer's system design and reducing time to market.
