There are a large number of IoT platforms
for design engineers to choose from. And more every day. These platforms very
greatly in performance, power, and tool sets, but, generally speaking, one
of them is right for your project. Why build your own module? Versions definitely
worth looking into include the set of four from Samsung called ARTIK.

Samsung has added to its smart IoT platform
offerings with two new modules, ARTIK 0 and ARTIK 7, and new cloud device
management capabilities.

The ARTIK 0 family
of modules are the lightest weight, lowest power, and lowest cost versions.
They target HVAC, lighting, industrial sensors, and personal health
monitoring. ARTIK 0 modules (020 and 030 versions) are built on a power-optimized
Cortex-M4 based processor with DSP Extensions, an FPU, and support for low-power
wireless standards such as the ZigBee, Thread, or Bluetooth Smart. They
include networking stacks, RF components, and pre-certification for
regulatory approval.


The Bluetooth 4.2 Compliant 020 version
features 256 Kbytes of flash, a 2.4 GHz radio, an integrated antenna, TX
power up to +8 dBm, RX sensitivity down to -92 dBm, and a range of up to
200 meters. The radio takes 8.7 mA in RX.  The small 12.9 x 15.0 x 2.2 mm module
operates from 2.4 to 3.6 V with an internal DC-DC converter and requires 78
µA/MHz typical using a 38 MHz RC oscillator running CoreMark from flash.
Standby is as low as 0.86 µA with RAM retention and RTC. It has a 12-bit 1
Ms/s A/D converter, a D/A, counter and timers, and hardware cryptographic
acceleration. The 030 version features mesh networking.

The ARTIK 7 modules are intended for
high-end gateways and multimedia applications. This powerful module has an
8-core 64-bit Cortex A-53 based processor, the modules are able to run
local data analytics to improve latency and responsiveness. It has 1
Gbyte of 800 MHz DDR3 and 4 Gbytes of eMMC flash. The module includes Wi-Fi,
Bluetooth, ZigBee, Thread, and Gigabit Ethernet MAC interfaces. It has a high-end multimedia processor
and a 3D graphics accelerator, and its pre-installed Linux OS speeds time
to market. The module is RF pre-certified and features enterprise-class
security with a secure point to point authentication and data transfer
function and trusted execution environment. It also has a six channel A/D
converter and a camera interface.

Power management of the ARTIK 710 module is controlled
by a single PMIC with five high efficiency DC-DC converters and ten LDO

The modules work out of the box with
the ARTIK Cloud, an open data-exchange platform that connects devices, applications,
and other clouds, enabling the interoperability. Designers can uniquely
identify each device, monitor its connectivity status, manage properties, firmware,
and battery levels, and remotely execute functions.
