About nRF24AP2-USB


Based on Nordic’s class-leading nRF24L01+ transceiver core, the nRF24AP2-USB integrates an ultra-low power 2.4GHz transceiver, ANT Wireless’ production-proven ultra low power ANT protocol stack, Full-Speed USB 2.0 compliant interface and 4 to 5.25V voltage regulators to create a true Single-Chip-Connectivity solution. The chip can be powered directly from a USB port, thus supporting compact USB dongle designs.


The nRF24AP2 core provides a range of benefits including substantial enhancements in wideband blocking and intermodulation as well as 5dB of extra sensitivity compared to its predecessor (the nRF24AP1). This extra sensitivity increases immunity to disturbance from other 2.4GHz sources in the vicinity. The ANT protocol stack implementation includes new features such as support for up to 8-channels, proximity search, frequency agility, and continuous scanning mode.


The device operates at a peak current of just 17mA. Average operating currents are in the microampere range (for example, in simple broadcast mode, average operating current is 9µA) leading to extended operation from small coin cell type batteries.


The 8-channel nRF24AP2-USB is an advanced and flexible product specifically designed for ANT hubs. Supporting up to 8-channels and without compromising power consumption, provides the same advanced feature set as Nordic's existing 8-channel nRF24AP2-8CH ultra low power (ULP) wireless solution, but exchanges the latter's UART interface for a Full-Speed USB 2.0 compliant host interface. This makes the nRF24AP2-USB ideal for both compact ANT USB dongles and embedded systems where a USB host interface is preferred.


The device is fully interoperable with existing Nordic Semiconductor nRF24AP1 ANT chipsets and supports the ANT+ managed network alliance platform, assuring interoperability between wireless products from different vendors.
