BlueNRG-M2 – Very low power application processor module for Bluetooth® low energy v5.0

The BlueNRG-M2 is a Bluetooth® low energy system-on-chip application processor certified module, compliant with BT specifications v5.0 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.
