The 2.4 GHz transmitter and receiver module is the most special one among many wireless transceiver modules. Its working frequency band is the only universal ISM frequency band that can be used worldwide: 2400MHz, so its application market is very broad.
The 2.4 GHz transmitter and receiver module made by the SX1280/SX1281 LoRa module launched by Semtech and the nRF24L01+ module launched by NORDIC is the most common on the market. Many customers don’t know whether they should choose the LoRa module LoRa1280/LoRa1281 or the nRF24L01+ module when choosing the 2.4 GHz transmitter and receiver module.
LoRa1280 and LoRa1281 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
This LoRa module 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 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.
RF2401Pro is a high integrated 2.4 GHz transmitter and receiver module, which adopts Nordic’s RF chip nRF24L01+.
RF2401Pro uses lead-free process for production and testing strictly and has obtained many certifications such as FCC ID, IC ID and ROHS.
Note: This module got FCC certification, FCC ID is 2AD66-RF2401PRO.
