Part number | product type |
Lora1280F27-TCXO | sx1280chip,0.5ppm TCXO Temperature compensated crystal |
Lora1280F27 | sx1280chip,10ppm Industrial grade crystal oscillator |
Lora1281F27 | sx1281chip,10ppm Industrial grade crystal oscillator |
There are three types of modules in LoRa128XF27 series:LoRa1280F27-TCXO, LoRa1280F27 and LoRa1281F27. Users can choose one of them according to their practical application, the specific differences are as follows:
Module type | Built-in chip | Crystal |
Certification
|
Lora1280F27-TCXO | SX1280 | 0.5ppm industrial grade TCXO temperature | — |
Lora1280F27 | SX1280 | 10ppm industrial grade crystal oscillator | CE & FCC |
Lora1281F27 | SX1281 | 10ppm industrial grade crystal oscillator | CE & FCC |
LoRa128XF27 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.And Lora1280F27 and Lora1281F27 have obtained CE and FCC certification.
This series of modules are designed based on the original sx1280/sx1281 RF chip from Semtech,and the matching of the PA circuit makes the output power of the module up to 500mW(+27dBm). In addition, the LoRa1280F27-TCXO module is also equipped with an industrial-grade high-precision TCXO temperature-compensated crystal oscillator, hich guarantees stable frequency output under harsh environments such as high and low temperature. The high penetration performance of the 2.4GHz frequency band combined with the LoRa modulation enables the module to have high receiving sensitivity and environmental anti-interference ability. The whole series of modules are widely used in applications requiring long-distance 2.4GHz transmission.

Communication 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 wires and spring antenna, and can also be used for SMA adapter straight/elbow/folding rods, small suction cups, etc. Users can purchase antennas according to their own application environment. In order to make the module work optimally, it is recommended to use the antenna from our company.

The following principles should be followed during antenna use to ensure the best communication distance of the module:
The antenna should not be close to the ground surface, and the surrounding area should be kept away from obstacles;
If the suck antenna is purchased, the lead wire should be straightened as much as possible, and the base should be attached to the metal object;
