DA14531 Module Front

The DA14531 SmartBond TINY™ Module is the Bluetooth® low energy solution that will power the next 1 billion IoT devices through ease of use.

The DA14531 SmartBond TINY™ Module, based on the world’s smallest and lowest power Bluetooth 5.1 system-on-Chip, brings the DA14531 SoC advantages to an integrated module. It just requires a power supply and a printed circuit board to build a Bluetooth application.

The module is targeting broad market use and will be certified across regions providing significant savings in development cost and time-to-market.

It comes with an integrated antenna and easy to use software making Bluetooth low energy development easier than ever before.

This awesome combination takes mobile connectivity to applications previously out of reach, enabling of the next billion IoT devices, with SmartBond TINY™ at their core.
