Features The NRF24L01 wireless module + power amplifier + LNA is a powerful and highly sensitive wireless data transmission module specially developed for 1100m ultra-long data transmission. NRF24L01P+Power Amplifier+LNA wireless module works in the 2.4G frequency band unlicensed and can support point-to-point applications, and can also form a star network. Digital transmission chip NRF24L01+, which is a powerful power amplifier and LNA chip, radio frequency switch, bandpass filter, etc. adds. And they form a professional fully two-way RF power amplifier, greatly increasing the effective communication distance. In the radio frequency part, a lot of optimization and tuning is done to make the transmission efficiency become the highest and the harmonics the smallest, so that the NRF24L01P + power amplifier + LNA wireless module has the lowest radio frequency interference with external equioments, and it is not susceptible to interference from other equioments, which greatly improves the stability of work. And the NRF24L01P+power amplifier+LNA wireless module is highly integrated and easy to embed into any product with limited space. Customers need to add a microcontroller unit to control the NRF24L01P+power amplifier+LNA through the serial peripheral interface port. Function: 1.
