Module Introduction:
RF2500B wireless module, operating in the 2.4GHz ISM / SRD band-free license to use, using CC2500 multi-channel RF transceiver. CC2500 is an ultra-low-power wireless applications industrys lowest system cost multi-channel wireless products, a powerful digital processing features, so using only a low-cost MCU can build a high-performance radio frequency systems, including many very useful The digital functions, such as an entire packet handling, FIFO buffers, clear channel assessment, and wireless wake-up, etc., can be widely used in consumer electronics products (such as wireless keyboard, mouse, game controllers), wireless audio transmission (such as wireless microphones, wireless headset, wireless speakers), etc.
Performance and features:
(1) Operating voltage: 1.8V ~ 3.6V, recommended close to 3.6V, but can not exceed 3.6V
(2) 2400-2483.5 MHz of the ISM and SRD band, license-free use
(3) The maximum operating speed of 500kbps, support 2-FSK, GFSK and MSK modulation
(4) High receiver sensitivity (1.2kbps under -110dBm, 10kbps under -101dBm, 250kbps at -90dBm, 1% packet error rate)
(5) Built-in hardware CRC error detection and multipoint communication address control
(6) low power consumption: TX: at 0dBm to 21.2mA RX: at 250kbps is 13.3mA;
(7) Programmable control of output power, maximum output power of 0dBm, the minimum -10dBm, the data rate can vary between 1.2kbps to 500kbps.
(8) to support low power electromagnetic activation function, external interrupts, external interrupt or RTC wake
(9) to support automatic cleaning before transmission channel access (CCA), namely carrier sense system
Suitable frequency hopping system (10) fast frequency synthesizers bring change
(11) The module can be software set address, software programming is very convenient
(12) Standard DIP pitch interfaces for embedded applications
(13) Separate 64-byte RX and TX data FIFO
(14) a few external components, high reliability
(15) module visible straight line communication distance 20 m -70 m
(16) Module size 28mm * 22mm (PCB-board antenna)
