Galileo is a microcontroller board based on the Intel? Quark SoC X1000 Application Processor, a 32-bit Intel Pentium?-class system on a chip (SoC). It is the first board based on Intel? architecture designed to be hardware and software pin-compatible with shields designed for the Arduino Uno R3.
The Galileo board is also software-compatible with the Arduino Software Development Environment, which makes usability and introduction a snap. In addition to Arduino hardware and software 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 8 MByte NOR flash come standard on the board.
The COM10U is one USB to RS232/TTL coverter, have one 3.5mm Jack being designed to debug the Galileo board. The USB to RS232/TTL Converter module provides a simple method of adapting legacy serial units with RS232 interfaces, to modern USB ports. This is accomplished by using the industry standard FTDI FT230X USB-Serial bridge IC.
