nRF24L01+PA+LNA with Antenna 2.4GHz Wireless Transceiver

Arduino and Raspberry Pi compatible wireless 2.4GHz transceiver 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 Resources nRF24L01+ Datasheet RFX2401C RFeIC (PA and LNA) Datasheet Arduino.cc nRF24L01 Library Arduino and Raspberry Pi nRF24L01+ Tutorial RF24 Master Library (GitHub Page) RF24 Master Library (.zip file download) nRF24L01+ with Gadgeteer and installer for .NETMF 4.3 (Barrett Simms) Castellations Pinout
