Product Description
This wireless module enables communication between microcontrollers and other electronic systems. The interchangeable RF chip determines the transmission protocol. NRF24L01 uses the 2.4 GHz band with a high data rate, while CC1100, CC2500, and A7105 offer alternative frequency bands and modulation methods. The choice of chip depends on the requirements of the application.
The module communicates with the microcontroller via SPI and requires only a few connections. It operates at 3.3 V; a logic level converter is required for connection to 5 V boards. The external antenna enables ranges of up to approximately 100 m in open terrain, although obstacles and interference can reduce the actual distance.
Typical applications include wireless sensor networks, in which distributed sensors collect their measurements centrally, and the remote control of mobile robots and drones. The module is also suitable for transmitting measurement data over longer distances in laboratories or buildings. One specific example is a wireless temperature sensor network in which several NRF24L01 modules send data from different rooms to a central data logger.
A microcontroller with an SPI interface and a development environment for programming the wireless module are required. The RF chip is inserted into the socket and must be compatible with the microcontroller firmware. A logic level converter is essential when using the module with 5 V systems.
Safety Information
This module is intended exclusively for building prototypes and for testing and development purposes. Do not touch the antenna while the module is in operation. When working on the power supply or if you are unsure about the correct wiring, consult a qualified electrician before commissioning the module.
