1. Product description
At present, most foreign countries use 915MHz frequency band for data
transmission, 915MHZ LORA MODULE is a module developed for foreign markets ,
The module uses SX1276 wireless spread spectrum chip.
The module uses SX1276 wireless spread spectrum chip.
SX1276 is a high performance, low power, long distance micro power wireless
transmission module, Internal automatic spread spectrum computing and preamble
CRC error correction, Do not change any data and protocol of the user, Using half
duplex transparent transmission mechanism, Realize serial wireless receive and send
instead of cable transmission function, It is suitable for low power applications such
as data acquisition.
CRC error correction, Do not change any data and protocol of the user, Using half
duplex transparent transmission mechanism, Realize serial wireless receive and send
instead of cable transmission function, It is suitable for low power applications such
as data acquisition.
RF chip based on spread spectrum frequency hopping technology, The stability, anti-
interference ability and receiver sensitivity are beyond the existing GFSK module,
Configuration of low power high speed processor, data processing ability, operation
speed has been improved.
Configuration of low power high speed processor, data processing ability, operation
speed has been improved.
The user can configure the module's working frequency, serial port rate, spread
spectrum factor, spread spectrum bandwidth and other parameters flexibly according
to the actual needs of the PC software configured by the company, and the operation
is simple, It's very convenient to use.
