rsbrs02ab

rsbrs02ab low power bluetooth module uses rs02a1-b chip of rf-star as the core processor. the module runs in 2.4 ghz ism band, gfsk modulation mode (gaussian frequency shift keying), 40 channel 2 mhz channel gap, 3 fixed broadcast channels, 37 adaptive automatic frequency hopping data channels. the physical layer can be combined with the classic bluetooth rf into a dual-mode device, and the 2 mhz gap can better prevent interference of adjacent channels.

  • transmit power： 0dbm
  • communication distance： 150m
  • core programme： rs02a1
  • bluetooth version： bt 4.2
  • core strengths： low power consumption

rf-star rsbrs02ab cheap bluetooth uart spi module ble 4.0 module high temperature

 

rf-star's rsbrs02ab bluetooth module is built upon its properiatary rs02a1-b ble soc that features ultra low power consumption (ble tx with ldo: 10.6 ma @ 0 dbm,ble rx with ldo: 8.8 ma @ 1 mbps), good noise reduction and high sensitivity. with advantages of low power consumption, compact design, long transmission distance and strong anti-interference capability, the module can be widely used in low power local area network communication. it is embedded with high performance serpentine pcb antenna and comes with stamp style hardware interface design.the module can be used to develop consumer electronic products and phone peripherals over ble4.2. it optimizes the reliability of operations, signal transmission distance and anti-interference capability, facilitates mutual operations between various devices, and significantly improves the expected life cycle of batteries.
