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).
Module size: 27.8mm*14.4mm*4m
