The nRF24L01 PA LNA Wireless Transceiver Module is the long-range version of the popular 2.4GHz radio frequency (RF) module. At Electrapac, we recommend this module for developers and robotics enthusiasts in Bangladesh who need reliable, wall-penetrating communication for drones, RC planes, and industrial remote monitoring systems.Product OverviewWhile the standard nRF24L01 module is limited to short distances, this version is equipped with a Power Amplifier (PA) and a Low Noise Amplifier (LNA). Together with the included external SMA antenna, these enhancements allow the module to achieve a line-of-sight range of up to 1000 meters (1km). It operates in the license-free 2.4GHz ISM band and uses the SPI protocol for easy integration with Arduino, Raspberry Pi, and ESP32.Key Features for Electrapac CustomersLong-Distance Mastery: The combination of the PA (Power Amplifier) for boosting the signal and LNA (Low Noise Amplifier) for catching weak signals makes this one of the most powerful 2.4GHz modules available.External SMA Antenna: Unlike PCB trace antennas, the included high-gain antenna can be repositioned or upgraded to further improve signal stability in obstructed environments.Auto-Acknowledge & Re-transmit: Built-in hardware logic automatically handles packet acknowledgment and re-transmission, ensuring your data arrives intact without bloating your code.Ultra-Low Power consumption: When not transmitting, the module can enter a "Power Down" mode consuming only 900nA, making it suitable for long-term battery-operated sensors.Multi-Device Networking: One module can communicate with up to 6 other modules simultaneously, perfect for creating a mesh network of sensors.Wiring & Stability GuideThe Electrapac nRF24L01 uses an 8-pin interface. Correct wiring and power filtering are essential for success:VCC (Pin 2): Connect ONLY to 3.3V. Connecting this to 5V will destroy the module immediately.SPI Pins: Connect MOSI, MISO, and SCK to the corresponding SPI pins on your microcontroller.CE & CSN: These can be connected to any digital pin for software control.Pro-Tip for Stability: These long-range modules are very sensitive to "noisy" power supplies. If you experience connection drops, solder a 10uF to 100uF Electrolytic Capacitor directly across the VCC and GND pins on the module. This filters out voltage spikes and provides the "burst" current needed for 1km transmissions.Primary ApplicationsRC Vehicles & Drones: Providing a long-range, interference-resistant link for flight control and telemetry.Wireless Sensor Networks: Collecting data from multiple remote nodes (e.g., across a large farm or factory floor).Remote Control Systems: Controlling gates, garage doors, or industrial machinery from a distance.Custom Game Controllers: Creating high-speed, lag-free wireless inputs for DIY gaming rigs.Walkie-Talkies: Digital voice transmission projects for short-to-medium distance communication.Why Shop at Electrapac?We source our nRF24L01 PA LNA Modules with high-quality SMA connectors and genuine Nordic Semiconductor chips to ensure maximum range and durability for our customers.
