AT3 Chipsets 
AT3 family of chipsets comprises an ANT MCU and a 2.4GHz radio chip nRF24L01+ or nRF24L01 from Nordic Semiconductor. Both chips are the best-in-class on power consumption. AT3 chipsets provide a comprehensive solution to building a wireless sensor network consisting of nodes from simple sensors to complex hubs. A common pin-out and identical footprint enables easy product and system development, upgrade, migration and maintenance.
SensRcore, an easy-to-use design platform to build wireless sensors, is equipped in the AT3 chipsets for wireless sensors. Many other enhanced ANT features are introduced through AT3 product family such as scanning channel, low priority search, channel ID list, channel transmission power control, using serial number in channel set up etc.
The AT3 family products is so-far the lowest power consumption solution of ANT.
