Product Information

Back to top
The nRF24AP2-USB is a highly integrated single-chip 8-channel ANT™ Connectivity IC. It includes an ultra low power 2.4GHz RF transceiver and a fully embedded enhanced ANT protocol stack, and features a full-speed USB 2.0-compliant host interface. With an integrated voltage regulator enabling it to be powered directly from the USB VBUS, the nRF24AP2-USB is ideally suited for ultra-compact ANT USB dongles or built-in applications where a USB host interface is more suitable than the serial interface provided by the Nordic nRF24AP2-8CH.

The integrated 2.4GHz RF transceiver core is based on the nRF24L01+ and provides significant sensitivity and co-existence performance improvements compared to the previous generation nRF24AP1. The on-chip ANT protocol stack features full compatibility for all ANT+ profiles, and includes advanced features such as: Scanning Channel for applications demanding low latency, Improved Channel Search for less impact on active channels, Per channel-based TX Output Power Control, and a Frequency Agility mode for improved co-existence performance.

The nRF24AP2-USB is available in a 5 x 5mm 32-pin package.

Figure 1. shows a network in which a network node with nRF24AP2-USB embedded, communicates with up to eight ANT nodes. An example might be a computer collecting data from a hub (a watch) in a portable ANT sensor network containing several sensors (like heart rate-, speed and distance sensors). The 8-channel nRF24AP2-USB node can of course also set up ANT channels with other nodes (gym equipment, for instance). The information collected though nRF24AP2-USB can then be used either locally or shared with others over local networks or internet.
