Detailed Description:

The NRF24L01+PA+LNA is a 2.4GHz ISM band wireless transceiver module with extended range capabilities. Featuring a built-in power amplifier (PA) and low noise amplifier (LNA), this module greatly enhances communication distance and signal reliability over the standard NRF24L01. It supports up to 2 Mbps data rate, SPI communication, and multi-device networking using unique addressing.

The included external SMA antenna provides directional performance and better signal gain, making this module suitable for remote sensing, wireless control, and IoT systems with demanding communication requirements.

Key Features:

• Based on Nordic NRF24L01+ transceiver chip

• Built-in PA (Power Amplifier) and LNA (Low Noise Amplifier)

• Operating frequency: 2.4GHz ISM band

• Long range communication: up to 1000 meters (line of sight)

• Comes with detachable SMA Antenna

• Supports data rates of 250kbps, 1Mbps, and 2Mbps

• Low power consumption with auto power-down mode

• 6 data pipes for multi-point communication

• SPI Interface – easy to connect with Arduino, STM32, Raspberry Pi

• Onboard LED status indicator

• Compact PCB with RF shielding

Technical Specifications:

Use a 3.3V regulator and decoupling capacitor (10uF recommended) for stable operation.

How to Use:

1. Connect to microcontroller via SPI pins (MISO, MOSI, SCK, CSN, CE).

2. Use 3.3V regulated power; avoid using 5V directly.

3. Install RF24 library in Arduino IDE.

4. Upload sketch to set up sender/receiver nodes.

5. Communicate wirelessly using addresses and data pipes.

#include
RF24 radio(9, 10); // CE, CSN
const byte address[6] = "00001";

void setup() {
  radio.begin();
  radio.openWritingPipe(address);
  radio.setPALevel(RF24_PA_HIGH);
  radio.setChannel(108);
  radio.stopListening();
}

void loop() {
  const char text[] = "Hello!";
  radio.write(&text, sizeof(text));
  delay(1000);
}
