AP2 Modules (EOL)


ANT transceiver module using nRF24AP2-8ch, an ANT network processor from Nordic Semiconductor embedded with enhanced ANT core stack.  An F antenna is integrated on the  20mm x 20mm PCB board. Two models: ANTAP281M4IB and ANTAP281M5IB.

The module has been certified to comply with radio regulation or standards covering global markets that include North America, Europe, Japan, Australia and New Zealand. The RF certified  module eases the burden for application and system developers from extensive RF and antenna design, and regulatory compliance testing, allowing for quicker time to the market. The module is ideal to build control or hub nodes of a wireless sensor network.
