Installing Drivers for the Arduino 101

Now that the Curie Core is installed, you can connect the board to the computer using a standard USB cable. The very first time your computer may go through the new hardware installation process.

Whenever an user wants to install the IDE form the zip file, or the windows store and installs the 101 board from the board manager the driver isn’t installed and therefore the board is not recognized.

This issue is easily solved doing a manual installation

Due follows the 1.0 pinout:

TWI: SDA and SCL pins that are near to the AREF pin.
The IOREF pin which allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V.
An unconnected pin, reserved for future use

• LINK: indicates the presence of a network link and flashes when the Shield transmits or receives data

USB Over-current Protection

The Arduino Mega 2560 R3 Board has a resettable polyfuse that protects your computer’s USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port. The fuse will automatically break the connection until the short or overload is removed.

Input and Output

Each of the 50 digital pins on the Mega R3 Android Accessory Development Kit (ADK) can be used as an input or output; using pin Mode(), digital Write(), and digital Read() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA . has an internal pull-up resistor (disconnect by default) of 20-50k Ohm. In addition, some pins have specialized functions:

• Serial : 0 (RX) and 1 (TX), Serial 1: 19 (RX) and 18 (TX), Serial 2: 17 (RX) and 16 (TX), Serial 3: 15 (RX) and 14 (TX). Use to receive (RX) and transmit (TX) TTL serial data. Pins 0 and 1 are also connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
• External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attach Interrupt() function for details.
• PWM: 2 to 13 and 44 to 46. Provide 8-bit PWM output with the analog Write() function.
• SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). These pins support SPI communication using the SPI library. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Uno, Duemilanove, and Diecimila.
• USB Host: MAX3421E.

This board can be powered via the micro-USB connection with 5VDC voltage. If the board is powered through the Vin pin, a regulated 5VDC must be applied. There is no on-board voltage regulator for higher voltages, which will damage the board. The Yún is also compatible with PoE power supply but in order to use this feature, a PoE module is mounted on the board or a pre-assembled board can be used.

This board is an ideal solution when designing connected devices and Internet of Things (IoT) projects. It is a combination of the power of Linux and the ease of use of Arduino. In addition to Linux commands like the cURL, the user can write own shell and python scripts for robust interactions.
