MakerFocus 2pcs nRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module 2.4G 1100m with SMA Antenna for Arduino
Product Description
MakerFocus 2pcs nRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module 2.4G 1100m with SMA Antenna for Arduino
- Main Function: Enhances the wireless communication performance of the nRF24L01+ chip by integrating a power amplifier (PA) and a low-noise amplifier (LNA). PA amplifies the transmission power from the standard 0dBm to approximately +22dBm, significantly expanding the signal coverage range; the LNA optimizes the sensitivity at the receiving end, reduces noise interference, and ensures stable data reception at long distances
- Communication Range: Equipped with an SMA interface for connecting high-gain antennas, the communication range exceeds 1,100 meters in open environments at 250Kbps and over 520 meters at 2Mbps high-speed rates
- Low Power Consumption: Transmission mode current is only 11.3mA, and reception mode is 13.5mA. Supports SPI interface direct connection to MCU, enabling quick integration into existing systems
- Wide Application: It can be widely used for wireless communication between modules, such as wireless remote control, somatosensory devices, RFID, NFC, smart grid, smart home, wireless audio, etc
- Instruction Manual: Please obtain the example link from the Product Guides and Documents below
2pcs Wireless Module NRF24L01+PA+LNA in Antistatic Foam Arduino Compatible with Antenna
Specifications:
The nRF24L01+ is a 2.4GHz ISM band transceiver
Range: 800+ meters line of sight
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
