Specification:

• Operating frequency range： 433.4-473.0MHz
  

• Power supply voltage : 3.2 V -- 5.5 V.(if the modules working long hours in emission state, suggested that when the power supply voltage is greater than 4.5 V , you need concatenating a 1N4007 diode to avoid module built-in LDO got fever)

• Default communication distance : about 600 m (communication distance is adjustable up to 1000 m, air baud rate 5000 BPS).

• Default idle current: 16 MA (modules in different working mode of different current).

• Mini size,only 27.8mm*14.4mm*4mm.
