Telemetry Wireless LoRa Ra-01 SX1278 433M 18Dbm Spread Spectrum + Antena

Anxinke LoRa series modules (Ra-01/Ra-02) are designed and developed by Anxinke Technology.
The radio frequency chip SX1278 mainly uses LoRa™ remote modem for ultra-long-distance spread spectrum communication
Letter , anti- interference is strong, a large extent possible to reduce current consumption.
With SEMTECH’s LoRa™ expertise with the advantage of modulation technology, SX1278 has a high sensitivity of over -148dBm and a power output of +20dBm,
Transmission distance stay away, high reliability. At the same time, compared with traditional modulation technology,
LoRa™ modulation technology is it also has 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, Ra-02 work frequency 433M, mainly for 433M network
