• Includes 2.4GHz 2.2dBi duck antenna
  
• Signal PA (Power Amplifier) and LNA (Low-Noise Amplifier) extends the range of this module considerably
  
• Applications: wireless peripherals, remote control systems such as RC vehicles and consumer remote electronics, wireless voice transmission such as VoIP, wireless sensor networks, wireless networks, home and commercial automation

Product Contents

• 1 - nRF24L01+ module with PA and LNA
  
• 1 - 2.4GHz 2.2dBi Duck Antenna

Specifications

• The nRF24L01+ is a 2.4GHz ISM band transceiver
  
• Range: 800+ meters line of sight (refer to Important Note section below)
  
• Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)
  
• A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps).
  
• The on-chip voltage regulator accepts supply voltages from 1.9 to 3.6V.
  
• The module has 5V tolerant inputs which allows for direct connection of SPI pins to the Arduino.
  
• Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast
• Automatic Gain Control (AGC).
  
• The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.
  
• Auto-acknowledge and auto-retransmit abilities
  
• Board dimensions, excluding pins: 15.5mm (0.61") width x 40.7mm (1.6") length x 12.2mm (0.48") height
  
• Dimensions of antenna, when angled at 90 degrees: 87mm (3.43") height x 9.5mm (0.37") diameter

Important Note

• To maximize the transmission/reception distance (range) we recommend the following:
  
  • Using a slower data rate, preferably 250kbps
    
  • In addition to the GND header pin we recommend also connecting your source ground to the ground through-holes or castellations near the brass antenna connector
    
  • Adding a 10uF capacitor across GND and V+ to assist with power demands during transmitting and receiving
    
• Using a dedicated 3.3V power source instead of an Arduino's 3.3V supply, a good 3.3V regulator such as the LD33V works well
  
• The module will work without the above recommendations but following the above recommendations will increase the module's total range
