Description

The

BlueNRG-M2 is a Bluetooth® low energy system-on-chip application processor

certified module, certified under BT specifications v5.2 and BQE qualified. The

BlueNRG-M2 module supports multiple roles simultaneously and can act at the

same time as Bluetooth master and slave device. The BlueNRG-M2 is based on the

BlueNRG-2 system-on-chip and entire Bluetooth low energy stack and protocols are

embedded into module. The BlueNRG-M2 module provides a complete RF platform

in a tiny form factor. Radio, embedded antenna and high frequency oscillators are

integrated to offer a certified solution to optimize the time-to-market of the final

applications. The BlueNRG-M2 can be powered directly with a pair of AAA batteries

or any power source from 1.7 to 3.6 V.
