DESCRIPTION
Ra-01 LoRa SX1278 Module Spread Spectrum Module SPI Interface N7R26432
LoRa series modules (Ra - 01 / Ra - 02) by essence can design and development of science and technology, this series of module
theRf chip SX1278 mainly adopts LoRa remote modems, used for long distance spread spectrum communication
The letter,Resistance toInterfere with strong sex, can maximum limit reduce current consumption.With LoRa are designed
The modulationTechnology, with more than 148 DBM SX1278 high sensitivity, + 20 DBM power output
the transport distanceFrom far and high reliability.At the same time, relative to the traditional modulation technology, LoRa modulation technology in the fight
Blocking and chooseAlso has obvious advantage, solve the traditional design scheme can't both distance,
Anti-interference and power consumptionThe problem.Ra, the Ra - 01-02 working frequency 433 m, mainly aimed at 433 m
Segment of the region, includingChina and southeast Asia.
The module features:
LoRa spread spectrum modulation technique
•Vast communication distance 15 km
+ 20 DBM - 100 mw constant power output voltage change
High sensitivity, low - 148 DBM
Half duplex SPI communication
Programmable bit rate is as high as 300 KBPS
Support for FSK, GFSK, MSK, GMSK, LoRa and modulation mode
127 db RSSI dynamic range
signal detection, automatic CAD model and super-fast AFC
Packet engine with , up to 256 bytes
Small size double row stamp hole patch encapsulation
With shielding shell
Spring antenna (Ra - 01) or external antenna (Ra - 02)
(Different batches may have different printed characters, but it does not affect the use)
Color: As Shown
Material: PCB
