Overview
The LoRa1262 wireless module uses Semtech's SX1262 device, which uses a high-precision TCXO crystal oscillator, ultra-low receive current and sleep current, and sensitivity of -148dBm. Built-in 64KHz crystal oscillator can wake up the microcontroller periodically under low power consumption. The module antenna switch is integrated and controlled by the chip, which saves the resources of the external MCU. The compact size and 22dBm (160mW) output power have great advantages in IoT and battery-powered applications

Communication antenna
1)Antenna
The antenna is an important part of the communication system. Its performance directly
affects the parameters of the communication system. The antenna impedance required
by the module is 50 ohms. The universal antenna has a spring antenna, and can also be
used to connect the straight head/elbow/folding rod shape, small suction cup, etc. through SMA. Users can purchase the antenna according to their own application
environment. In order to make the module work in the best working condition, it is
recommended to use this. The antenna provided by the company 

The following principles should be followed during antenna use to ensure the best
communication distance of the module:

• Try not to be close to the ground surface of the antenna, and it is best to stay away from
  obstacles;
• If the suction cup antenna is purchased, the lead wire should be straightened as much as
  possible, and the suction cup base should be attached to the metal object

FAQ:
a) Why module can not communicate properly?
1) The power supply is connected incorrectly and the module is not working properly;
2) 2) Check whether the frequency band of each module and other RF parameters are consistent;
3) 3) Is the module damaged?
b) Why transmission distance is not far as it should be?
1) Power supply ripple is too large;
2) The antenna types do not match, or not properly installed;
3) The surrounding environment is harsh, strong interference sources;
4) Surrounding co-channel interference;
