Supply voltage 3.2V ~ 5.5V. ( If the module you want to work long hours in emission-shaped state, the proposed series when the supply voltage exceeds 4.5V a 1N4007 diode, avoid heating module built LDO )
Default communication distance (open test): around 600m (the maximum communication distance is adjustable reach 1000m, the air baud rate 5000bps).
The default idle current: 16MA (modules in different operating modes different operating current).
Module size: 27.8mm 14.4mm 4mm.
Working frequency ratio range around ( 433.4-473.0MHz , up to 100 communication frequency channels)
Maximum 100mW hair transmit power (which can be set up set)
The module supports software upgrades. (We offer our customers a software upgrade)
The default factory settings: Operating mode FU3, baud 9600bps, communication channel CH001 (433.4M).
