Anxinke LoRa series modules (Ra-01/Ra-02) are designed and developed by Anxinke Technology.
The RF chip SX1278 mainly uses LoRa™ remote modem for ultra-long distance spread spectrum communication,
Strong anti-interference, can minimize the current consumption. Modulation with patented LoRa™ from SEMTECH
technology, SX1278 has high sensitivity of over -148dBm, power output of +20dBm, transmission distance
Long distance and high reliability. At the same time, compared with traditional modulation technology, LoRa™ modulation technology is more resistant to blocking and selection.
It also has obvious advantages in terms of solving the problem that the traditional design scheme cannot take into account distance, anti-interference and power consumption at the same time
The problem. The working frequency of Ra-01 and Ra-02 is 410-525MHz, which supports China and Southeast Asia.
