Bluetooth Low Energy RF Module Supports up to 8 Connections

April 07, 2020 by Paul Shepard

Panasonic has added the PAN1740A Series RF Module, an optimized version of the existing PAN1740 Series Module, offering a reduced boot time and supporting up to eight connections to allow greater flexibility to create more advanced applications.

The PAN1740A Series has a fully integrated radio transceiver and baseband processor for Bluetooth® 5.0 Low Energy.  It can be used as a standalone application processor or as a data pump in hosted systems.

The PAN1740A is optimized for remote control units (RCU) requiring support for voice commands and motion/gesture recognition. Its integrated Audio Unit (AU) offers easy interface for MEMS microphones over PDM, external codecs over wPCM/I2S and a Sample Rate Converter unit.
