Product description
1: The 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 LDO fever built in the module.
2: Default communication distance (open test): 600m (communication distance can be adjusted to 1000m, air baud rate 5000bps).
3: Default idle current: 16MA (the working current of modules is different in different working modes).
4: Module size: 27.8mm x 14.4mm x 4mm.
5: Working frequency range (433.4-473.0MHz, up to 100 communication channels) maximum 100mW transmission power (settable)
6: Module supports software upgrade. (We provide upgrade software for our customers)
7: Default factory settings: working mode FU3, baud rate 9600 bps, communication channel CH001 (433.4M).
