1 ANT AP2 Module
The ANT AP2 module is a drop-in module based on the reference design of nRF24AP2, a new generation of
ANT system on chip family from Nordic Semiconductor. An F antenna is integrated on the small-sized
20mm by 20mm board. The module has been certified to comply with radio regulation or standards
covering global markets include North America, Europe, Japan and Australia. The integrated module eases
the burden for application and system developers from extensive RF and antenna design, and regulatory
compliance testing, allowing quicker time to market. Able to support 8 ANT channels, the module is ideal
to build control or hub nodes of a wireless sensor network.
AP2 modules are currently available in the following varieties.
