The Nordic Semiconductor nRF24L01+ is a 2.4 GHz transceiver IC with an enhanced feature set over the original nRF24L01, including improved range, auto-acknowledge, auto-retransmit, and six data pipes (Multiceiver). It operates on a 1.9–3.6 V supply with 5 V tolerant input pins, making it straightforward to interface with a variety of microcontrollers.
Key Features
- 2.4 GHz ISM Band – 125 selectable channels (2400–2525 MHz)
- Up to 2 Mbps Data Rate – Plus a long-range 250 kbps mode
- 6 Data Pipes (Multiceiver) – Communicate with multiple transmitters simultaneously
- Auto-Acknowledge & Auto-Retransmit – Built-in reliable data transfer
- 32-Byte TX & RX FIFOs – Separate buffers for transmit and receive
- 1.9–3.6 V Supply – Low voltage operation with 5 V tolerant inputs
- Drop-In Compatible – Pin-compatible with the original nRF24L01
Ideal For
- Wireless sensor networks and IoT nodes
- Remote control and telemetry projects
- Arduino and microcontroller wireless communication
- Custom PCB designs requiring a compact RF transceiver

Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
