Key Features:-
Frequency: Operates in the 2.4 GHz ISM band.
Transmit Power: The presence of the Power Amplifier (PA) allows for adjustable transmit power levels, typically ranging from around +7 dBm to +20 dBm (1 mW to 100 mW). This increased power helps extend the communication range.
Receive Sensitivity: Enhanced sensitivity due to the Low Noise Amplifier (LNA), improving the module's ability to receive weak signals.
Antenna: The module comes with an external antenna connector using an SMA connector. This allows you to attach different types of antennas to suit your communication needs.
Communication Protocol: The NRF24L01 module uses a custom communication protocol that provides basic packet-based communication.
Data Rate: The module supports data rates of 250 kbps, 1 Mbps, and 2 Mbps, allowing you to choose the appropriate data rate for your application.
Voltage Range: Typically operates at 3.3V, but some versions might handle a wider voltage range.
Current Consumption: The exact current consumption depends on the transmit power, data rate, and operating mode. It can range from around 10 mA in standby mode to over 100 mA during transmission.
Operating Modes:
TX Mode: For transmitting data.
RX Mode: For receiving data.
Standby Mode: Low-power mode when not actively transmitting or receiving.
Compatibility: The NRF24L01 module can be used with various microcontrollers, such as Arduino, Raspberry Pi, and other development boards, as long as they have SPI communication capabilities.
Dimensions: The module's size is typically compact, often around 25mm x 15mm.
Applications: Commonly used in wireless sensor networks, remote control systems, home automation, IoT (Internet of Things) devices, and more.
