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 10 LDO regulators.
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.
