Description:
l NRF24L01P+PA+LNA module is carefully designed with high-speed 2.4G wireless transceiver chip NRF24L01P
l The module works in half-duplex, each module can receive and transmit, and at least two modules can be used to realize point-to-point wireless data communication
l Equipped with a 20dBm power amplifier chip, 10ppm high-precision chip crystal and high-precision inductors and capacitors, the maximum transmit power of the module is up to 20dBm (100mW), and the receiving sensitivity is increased by 15dB at the same time, and the performance is extremely stable
l A high-power and high-sensitivity wireless two-way 2.4GHz data transmission module specially developed for long-distance data transmission, works in the license-free 2.4G-2.5G ISM frequency band, can be applied point-to-point, and can also form a star network
l PA+LNA can reach more than 2500 meters under good conditions, with shielding cover, anti-interference, low radiation
Driver Description:
l This module is designed for nRF24L01P+RFX2401 IC, and its driving method is completely equivalent to nRF24L01P (or nRF24L01). Users can operate according to the nRF24L01P chip manual (see nRF24L01P manual for details).
l The CE pin is connected to the LNA enable pin. When CE=1, the LNA is turned on, and when CE=0, the LNA is turned off. This operation is completely consistent with the transceiver mode of the nRF24L01; that is, the user does not need to care about the LNA operation at all.
l If the user needs an automatic response, the CE pin must keep a high level during the transmission process, and the high level time cannot be greater than 10us as mentioned in the nRF24L01P manual. The correct operation is: CE=1 triggers the transmission, and only after the transmission is completed, CE=0 is set instead of CE=0 after 10us. The reason is: after the L01P is sent, it immediately switches to the receiving mode. At this time, if CE= 0, the LNA has been turned off, which will be detrimental to the receiving sensitivity.
