فرکانس 433MHz
Description:
The Ra-01 LoRa module is made by Ai-Thinker company, the manufacturer of the
ESP32S module, the module uses SX1278 IC, works on 433MHz frequency. It is a
high quality made module.
The RF chip SX1278 mainly uses LoRa™ remote modem for ultra-long distance spread
spectrum communication Letter , anti- interference is strong, it is possible to
minimize current consumption. With the help of SEMTECH’s LoRa™, The modulation
technology, SX1278 has a high sensitivity of more than -148dBm, +20dBm power
output, Transmission distance stay away, high reliability. At the same time,
compared with traditional modulation technology, LoRa™ modulation technology.
Ra-01 can be used for ultra-long distance spread spectrum communication, and
these devices also support high performance (G)FSK modes for systems including
WMBus, IEEE802.15.4g. The SX1287 deliver exceptional phase noise, selectivity,
receiver linearity and IIP3 for significantly lower current consumption than
competing devices.
There are also obvious advantages in blocking and selection, which solves the
problem that traditional design solutions cannot take into account distance,
Anti-interference and power consumption issues. Ra-01 working frequency is
433Mhz, mainly for 433Mhz network Regions.
LoRa provides significant advantages in both blocking and selectivity over
conventional modulation techniques, solving the traditional design compromise
between range, interference immunity and energy consumption.
