BMT NRF24L01+ 2.4GHz Transceiver Module SPI 250m Open Area

The BMT NRF24L01+ Transceiver Module is a compact 2.4GHz wireless transceiver based on the Nordic nRF24L01+ platform. Designed for embedded electronics, microcontroller projects and wireless communication systems, the module provides a simple SPI interface for exchanging data between a host controller and other compatible nRF24L01+ devices.

With an operating voltage of 1.9-3.6V DC, the module is suitable for low-voltage microcontroller applications. Its onboard PCB antenna eliminates the need for a separate external antenna, helping keep the overall installation compact and convenient.

The module supports selectable wireless data rates of 250kbps, 1Mbps and 2Mbps. The lower 250kbps data rate provides improved receiver sensitivity and can be used where communication range is more important than maximum data throughput.

Under suitable open-area conditions, the supplied product information specifies a communication distance of approximately 240m, while the product description references up to 250m in open areas. Actual range will depend on antenna orientation, interference, obstacles, data rate, power supply quality and environmental conditions.

• Receiving Current at 250kbps: Approximately 14mA
• Standby Current: Approximately 15 A
• Power-Off Current: Approximately 700nA

SPI Interface

The BMT NRF24L01+ communicates with a host microcontroller through an SPI interface. This makes it suitable for development boards and embedded controllers that provide compatible SPI communication.

The module can be integrated into wireless systems where a microcontroller needs to transmit or receive digital data without requiring a wired connection between devices.

Wireless Data Rates

The module supports three selectable communication speeds:

• 250kbps: Provides improved sensitivity and is suitable for applications where range and communication reliability are prioritised.
• 1Mbps: Provides a balance between data throughput and communication range.
• 2Mbps: Provides the highest supported data rate for applications requiring faster wireless data transfer.

The selected data rate can affect achievable communication distance and should be chosen according to the requirements of the application.

Onboard PCB Antenna

Unlike versions that require a separate external antenna, this module uses an integrated PCB antenna. This simplifies installation and keeps the module compact.

For best range, the antenna area should be kept clear of large metal objects and other sources of RF interference. Antenna orientation and installation position can also affect communication performance.

Communication Range

The supplied product specifications indicate an open-area communication distance of approximately 240m, with the product description referencing up to 250m under suitable conditions.

The actual usable range may be significantly shorter in buildings or areas with obstructions. The 2.4GHz operating frequency can be affected by walls, metal structures and other nearby 2.4GHz wireless equipment, including Wi-Fi devices.

For this reason, the stated range should be treated as an open-area reference figure rather than a guaranteed operating distance.

Applications

The BMT NRF24L01+ Transceiver Module can be used for a variety of wireless electronics projects, including:

• Arduino wireless projects
• Microcontroller communication
• Wireless sensor networks
• Robotics
• Robot cars
• Remote-control systems
• Home automation
• Smart-home projects
• IoT prototypes
• Wireless monitoring
• Remote data collection
• Wireless telemetry
• Electronic development projects
• DIY communication systems
• Multi-node wireless projects
• Embedded control systems

Compact Design

The module's compact construction makes it suitable for applications where PCB space is limited. The integrated PCB antenna further simplifies installation by removing the requirement for an external antenna assembly.

It can be incorporated into custom PCBs, prototype boards and development projects where low-voltage wireless communication is required.

Important Installation Notes

• Operate the module only within the specified 1.9-3.6V supply range.
• Do not connect the module directly to a 5V supply.
• Use a clean and stable power source for reliable wireless operation.
• Keep the PCB antenna area clear of large metal objects where possible.
• Avoid placing the module directly next to strong RF interference sources.
• Communication range varies according to the installation environment.
• Walls and other obstacles can significantly reduce the achievable range.
• Nearby 2.4GHz Wi-Fi and other wireless equipment may affect performance.
• Note: The stated approximately 240-250m range applies to suitable open-area conditions. Actual range depends on data rate, antenna orientation, obstacles, interference, installation and environmental conditions.
