G-NiceRF | LoRa1280-81 2.4ghz Range measurement wirelessly long distance module

There are three types of modules in LoRa1280-81 series:LoRa1280-TCXO、LoRa1280 and LoRa1281. Users can choose one of them according to their practical application, the specific differences are as follows:

This series of modules is designed based on the original sx1280/sx1281 radio frequency chip of Semtech in the United States. It uses LoRa's modulation mode, which improves the short communication distance of ordinary 2.4GHz modules. The whole series of modules use a 10ppm industrial-grade crystal oscillator, and the LoRa1280-TCXO module is also specially equipped with a higher-precision industrial-grade 0.5ppm TCXO temperature-compensated crystal oscillator, which guarantees stable frequency output under harsh environments such as high and low temperature. It also has the "time of flight" function, which can realize RF ranging applications.

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.
