Galileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip.

The Gen 2 board has the following limitations in libmraa:

• i2c is set at 400Khz speed cannot be changed without reloading kernel module
• i2c bus is shared with multiple devices, scanning it usually fails
• pwm period is set globally for all pwm channels, when changed this will halt all pwm channels
