The nRF24AP2-USB is a highly integrated 8-channel ANT network processor from Nordic Semiconductor that features enhanced ANT core stack and 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 dongle or built-in applications where a USB host interface is more suitable. The integrated 2.4GHz RF transceiver core is based on the nRF24L01+ and provides significant sensitivity and co-existence performance improvements. 

The nRF24AP2-USB is available in a QFN 5 x 5 package.
