with Connectivity
The MCU cog is a compact development platform enabling systemdesigners to design, build, test, and deploy ultra low power industrial
wireless IoT solutions quickly and easily. The EV-COG-AD3029LZ MCU cog
uses the ADuCM3029 ARM® Cortex®-M3 microcontroller, whereas theEV-COG-AD4050LZ uses the more powerful ADuCM4050 ARM Cortex-M4F
microcontroller. Both are designed to provide years of robust and secure
operation using coin cell batteries and are targeted toward smart
industrial, smart health, smart city, and smart infrastructure applications.
Expansion boards referred to as gears can be developed by the designer
to support specific sensor requirements. Analog Devices offers anexpander gear board as an example, which provides the designer withaccess to all of the microcontroller signals.

Open Source
The CrossCore® Embedded Studio™ is based on free, open-source
software, including Eclipse, GNU toolchain, GNU ARM Eclipse plugin, andother software. The ADuCM3029 IDE offers designers an easy to use
development tool with no code size limitations.

Prototyping
The MCU cog boards incorporate debugging capability and can be usedas standalone platforms for software debugging. The expander gear board
includes an industry-standard Arduino® shield socket should the designer
want to use commercially available shield boards for prototyping. It also
provides board space for the designer to solder additional components.

Wireless Connectivity
To allow the designer to experiment with different wireless connectivity
options, a range of high performance Analog Devices radio modules canbe connected directly to the MCU cog boards.
The EV-COG-BLEINTP1Z connectivity cog also connects directly to theMCU cog platform. It provides general-purpose wireless connectivity
over standard Bluetooth® LE and Wi-Fi. It also allows more advanced
designers with expertise in radio to develop their own protocols based on
the Analog Devices portfolio of performance radio transceivers, which aredesigned to plug into this connectivity cog board.

MCU Cog

Connectivity Cog

The gear houses the application specific sensors
and the data from sensors is read by the MCU.

The MCU on the MCU cog reads the sensor data,processes and interprets the data, and sends theinformation over the connectivity cog.

The connectivity cog contains one of Analog Devices’
connectivity solutions. This cog relays the information
sent by the MCU over the air.

Cloud
Cloud services are used to visualize and interpretthe data.
