Description

The nRF24L01 is a low-power, highly integrated 2.4GHz wireless transceiver from Nordic Semiconductor. It’s often used in short-range wireless communication applications like IoT, sensor networks, and wireless data transmission.

Here are the key specifications:

  • Frequency Range: 2.4 GHz ISM (Industrial, Scientific, and Medical) band
  • Modulation Type: GFSK (Gaussian Frequency Shift Keying)
  • Data Rate:
    • 250 kbps, 1 Mbps, and 2 Mbps selectable
  • Range:
    • Typically up to 85 meters in open space with a standard antenna (range can vary depending on environmental factors and antenna quality).
  • Power Supply Voltage:
    • 1.9V to 3.6V DC (operates with 3.3V most commonly)
  • Transmit Power:
    • +0 dBm (1 mW) to -18 dBm, adjustable for power savings and range optimization.
  • Receiver Sensitivity:
    • -94 dBm at 2 Mbps, -90 dBm at 1 Mbps (depending on data rate and conditions)
  • Current Consumption:
    • TX (Transmit mode): 11.3 mA (at +0 dBm)
    • RX (Receive mode): 13.5 mA
    • Standby mode: 26 µA
  • Antenna Type: PCB antenna or external antenna (if using the nRF24L01+ with an external antenna)
  • Interfaces:
    • SPI (Serial Peripheral Interface): Used to communicate with microcontrollers like Arduino, Raspberry Pi, etc.
  • Built-in Features:
    • Auto acknowledgment and retransmission
    • Data pipe (supports multiple communication channels)
    • Low power consumption for battery-powered devices
    • FIFO buffer for both transmission and reception
    • CRC (Cyclic Redundancy Check) for error detection
  • Form Factor: Compact 12-pin package (or in a module like the nRF24L01+ with external antenna).

Applications:

  • Wireless sensors and actuators
  • IoT (Internet of Things) devices
  • Remote controls
  • Wireless data transmission (such as in robotics or home automation)

The nRF24L01 is widely used due to its low power consumption, reliable communication, and compatibility with many microcontrollers (like Arduino). The range (85 meters) can be extended by using an external antenna version of the module (nRF24L01+).
