INTEL EDISON- A SOC based on Intel Atom The Intel Edison compute module is designed to lower the barriers to entry for anyone prototyping and producing IoT and wearable computing products. Intel Edison contains the core system processing and connectivity elements: processor, PMIC, RAM, eMMC, and Wi- Fi/BT. Intel Edison is a module that interfaces with end-user systems via a 70-pin connector. The Intel Edison compute module does not include any video input or output interfaces (MIPI CSI, MIPI DSI, HDMI, etc.). Internal image processing and graphics processing cores are disabled (ISP, PowerVR, VED, VEC, VSP, etc.). Intel Edison relies on the end-user support of input power.

Run example code Intel® Edison Arduino Expansion Board Assembly https://software.intel.com/en‐us/articles/intel‐edison‐arduino‐expansion‐board‐assembly Microswitch and USB Ports Details The slider switches between USB host mode and USB device mode. Device mode: The switch is toggled down and a micro‐USB cable can be used to turn the Intel® Edison into a computer peripheral. Device mode allows you to do such things as: program the board over USB, or mount the onboard flash memory like a disk drive. Host mode: The switch is toggled up and USB peripherals with a standard‐sized USB cable (such as mice, keyboards, etc) can be plugged into the Intel® Edison. USB host mode requires the use of an external power adapter. The Intel Edison board has three USB ports: The middle port (Micro A type) is used for the following: •Power through USB •Ethernet over USB •Uploading Arduino sketches •Updating the firmware by using the board as a storage device, like a flash drive The edge port (Micro A type) is used to create a terminal connection by serial over USB only. Power Through DC Plug If you are going to use more power intensive features such as Wi‐Fi, a servo motor, or an Arduino shield, use a DC power supply in addition to the device mode micro‐USB cable.

Arduino family of boards network storage having high popularity and large number of sold units featuring Some or all of these functionalities can be present including open access, reliability, robustness, standard connections and low prices, possesses large potential for implementation of also some specific not mentioned here. Mentioned autonomous remote measurement and control systems of various functionalities are quite general and do not pose limitations by levels of complexity. As Arduino boards can function themselves, as the real limits of IoT devices are mainly independently, they are complete small computer platforms that determined by processing power, speed, available memory, can perform various tasks requiring some kind of interaction with power consumption and similar characteristics. If the task for the outer world. Arduino boards can be used and programmed in some IoT device is too demanding, the possibility of logically various ways, and can be arranged in various combinations redefining the task so that more than one IoT device could be forming some typical implementation architectures that this paper used and combined to fulfill the given task, should be discusses.

  • Galileo Datasheet
    Galileo Datasheet Galileo Front Galileo Back Overview Galileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip (datasheet). It is the first board based on Intel® architecture designed to be hardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3. This is also known as the Arduino 1.0 pinout. Order Number: 329681-003US Galileo is designed to support shields that operate at either 3.3V or 5V. The core operating voltage of Galileo is 3.3V. However, a jumper on the board enables voltage translation to 5V at the I/O pins. This provides support for 5V Uno shields and is the default behavior. By switching the jumper position, the voltage translation can be disabled to provide 3.3V operation at the I/O pins. Of course, the Galileo board is also SW compatible with the Arduino SW Development Environment, which makes usability and introduction a snap. In addition to Arduino HW and SW compatibility, the Galileo board has several PC industry standard I/O ports and features to expand native usage and capabilities beyond the Arduino shield ecosystem. A full sized mini-PCI Express* slot, 100Mb Ethernet port, Micro-SD slot, RS-232 serial port, USB Host port, USB Client port, and 8MByte NOR flash come standard on the board.
