ANT has launched the AT3 family of modules featuring ANT's RF ultralow-power protocol, SensRcore wireless sensor development platform and consistent hardware footprint. Offering simplified design and integration as well as low cost in a variety of practical application-driven configurations, the modules handles all simple to complex wireless sensor network (WSN) sensor node and hub scenarios.

The AT3 drop-in FCC ready modules are a complete silicon solution intentionally engineered for ease of use, scalability and lowest power consumption enabling sensors to operate for up to three years on a coin cell battery. AT3 modules are integrated with an F antenna, reducing the need for RF design expertise. A common AT3 pin-out and 20mm x 20mm footprint enables easy network development, upgrading, migration and maintenance.

The ANT AT3 Module Family includes four standard modules delivered on one common hardware platform: 1 channel with SensRcore for simple sensor nodes; 4 channel and 8 channel with SensRcore for complex sensor nodes or sensor/hub combined nodes; and 8 channel ANT for complex hub.

The SensRcore development platform eliminates the need for an external host MCU and firmware programming for most wireless sensors. Instead, only simple point-and-click configurations or scripts are required.

"AT3's common platform dramatically changes the way engineers approach design," said Brian Macdonald, director, ANT. "With the AT3 family of modules, many things can be built on the same hardware which means less time and less capital investment with the assurance of the lowest possible power consumption on the market today."
