Description
Intel Galileo is a boot module based on a 32-bit Pentium-class processor: Intel QuarkSoCX1000. The board is compatible with popularArduino Uno, which means it works with ArduinoShieldoverlaysandis supported by Arduino IDE development environment. To start working on the module it is enough to connect to the computer viamicroUSB cable.
Galileo works with 3.3V and 5V overlays. The processor itself works with 3.3 V, however, the converter placed on the board changes the voltage on the outputs up to 5 V. Thanks to this module is compatible with original Arduino Uno Shield. In order to change voltage to 3.3 V, it is necessary to set appropriate jumper.
On the board, in addition to a high-performance Intel processor, there are also some on the board:
- Mini-PCI Express socket
- Ethernet port 100 Mb
- MicroSD cardslot
- RS-232 serial port
- USB port
- NOR flash memory 8 MB
Intel Galileo has communication interfaces specific to microcontrollers:
- I2C bus - SDA and SCL pins
- SPI bus - by default at 4 MHz
- UART serial interface - with programmable speed on RX(0) and TX(1) pins
- 14 digital pins - of which 6 can be used as an EDD signal
- 6 analogue inputs - marked with A0-A5 symbols, connected via a 12-bit resolution transmitter.
| The above mentioned interfaces are supported by standard Arduino libraries, for example, access to digital pins is realized by functions: pinMode(), digitalWrite(), digitalRead(). |
Intel architecture
The Galileo module is equipped with a 32-bit Intel Quark processor with the following parameters:
- Clocking: 400 MHz
- SRAM: 512 KB
- Single thread, 1 core and constant speed, making it easy to program
- Low power mode - CPU sleep mode
- Integrated real time clock (RTC) with power supply from a small 3 V round battery
Power supply
Intel Galileo requires a 5-volt power supply from the 2.1mm DC socket from the mains adapter included in the kit. The system can supply up to 80 mA from the I/O ports.
