Description

1: The power supply voltage is 3.2V~5.5V. (If the module needs to work in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the power supply voltage exceeds 4.5V to avoid heating of the module's built-in LDO)

2: Default communication distance (open ground test): about 600m (the maximum communication distance can be adjusted to 1000m, and the air baud rate is 5000bps).

3: Default idle current: 16MA (the operating current of the module is different under different operating modes).

4: Module size: 27.8mm × 14.4mm × 4mm。

5: Operating frequency range (433.4-473.0MHz, up to 100 communication channels) Maximum 100mW transmission power (settable)

6: The module supports software upgrade. (We provide customers with upgraded software)

7: Default factory settings: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).
