robotic.icu: 2pcs NRF24L01 + PA + LNA Posted in: Specs | by Brian Taylor | 2019 Jan 03
Model:NRF24L01 + PA + LNA
Package Includes:1pc Module
NRF24L01P + PA + LNA Division I for ultra-long-distance data transmission specially developed high-power and high sensitivity 2.4G wireless ISM band module NRF24L01P + PA + LNA wireless module to work on license-free, can be point-to-point applications, can also be composed of a star network,
NRF24L01P + PA + LNA wireless core module Norway NORDIC latest company high-performance wireless
The NRF24L01 + Chip Digital Transmission, with Professional Design Professionals Division full two-way RF high power PA power amplifier and LNA chip, RF switches, bandpass filters, etc., makes the effective communication distance to expand .
RF part, the Secretary has done a lot of matching debug optimization, emission efficiency to achieve the highest harmonic minimum
Does NRF24L01P + PA + LNA Wireless Module Equipment achieves a minimum of RF interference to the external, while not susceptible to interference from other devices, very high uploader.
High work stability.
Integration NRF24L01P + PA + LNA wireless module is very high, the size of only 41mm x 15.5mm, convenient built-in
In any tight space products, customers can increase an MCU through the SPI port to control NRF24L01P + PA + LNA.
Wireless module to complete the ultra-long-range system design completely eliminates the need for wireless data transmission to the RF part of R&D.
This is a 2.4ghz wireless transceiver module that utilizes the NRF24L01 chip. This version has a power amplifier and antenna to enable better range than the printed antenna traces. This module only accepts 3.3v on the VCC pin. Using more voltage than 3.3v will damage or destroy this module. It is advisable to use a dedicated 3.3v power supply as the 3.3v regulator found on Arduino micro-controllers may not be fully capable to power this unit properly in higher power modes.
A pinout diagram is provided in the product photos. Reference the datasheets for the microcontroller you are using to find out what pins correspond to the SS/CSN, SCK, MOSI, and MISO pins.
These transmit on the 2.4ghz wireless frequency which is shared by many wireless devices such as your wireless router. For best performance, utilize a wifi survey app on your phone to find out what wifi channels are most utilized and set this module to use a lesser utilized one. You should choose 1,6, or 11.
There are many libraries available for the Arduino development environment that make utilizing these modules easier. They are linked in the resources section.
These are very easy to use and robust wireless modules.
Their popularity means there is no shortage of libraries and examples for their use available online
Search for ”NRF24L01 Arduino” for plenty of examples including simple remote controls and mesh network configurations.
Range depends on a number of factors but 1000m+ with line of sight is possible.
These are not WiFi modules. If that is what you are looking for, you probably want an ESP8266.
