Very-Low-Power Application Processor Module for BLE v5.0

March 26, 2020 by Paul Shepard

The BlueNRG-M2 from STMicroelectronics is a Bluetooth low energy (BLE) 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.

Typical applications are expected to include: internet of things; smart home; building and industrial automation; smart lighting; remote and access control; fitness, wellness and sports; consumer medical; security and proximity; assisted living; and PC and smart phone peripherals.

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.
