Our Review

After integrating the 2,4 GHZ NRF24L01 Wireless Transceiver Module (2pcs) into several test builds, we found it to be a capable component for the price. Key specs include Frequency: 2.4 GHz ISM band, Data Rate: 250kbps / 1Mbps / 2Mbps, Range: up to 100m (open air).

Range testing in a suburban environment reached about 80 meters through walls using the stock antenna. In open air, 200+ meters was achievable at reduced data rate.

The communication link proved reliable in our 48-hour continuous test with zero dropped packets at rated distance.

The 2,4 GHZ NRF24L01 Wireless Transceiver Module (2pcs) earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.

What We Like

Simple serial/SPI interface for easy MCU integration
Configurable data rate and TX power for range vs. speed tradeoff
Onboard antenna works out of the box
Long range communication reduces infrastructure costs

Watch Out For

Limited data throughput compared to WiFi
Antenna placement affects range significantly
No built-in encryption on basic modules
