Nordic Semiconductor nRF24AP2 ANT™ Low-Power Wireless Solution
Nordic Semiconductor nRF24AP2 Single-Chip ANT™ Ultra-Low Power Wireless Network Solution is a low-cost, high-performance 2.4GHz ISM single chip transceiver solution for Ultra Low Power (ULP) networks. Th nRF24AP2 integrates the power efficient ANT protocol stack, industry-leading 2.4GHz RF technology, and a critical low-power oscillator and timing features. The second-generation single-chip ANT solution acts as a bridge between ANT networks and computers, Mac books, and the Internet. The nRF24AP2-USB supports up to eight ANT channels and is ideal for hubs. This solution provides worldwide 2.4GHz ISM band operation. Typical applications include sports, wellness, home health monitoring, home/industrial monitoring, and environmental sensor networks.Features
