Description: SCL and SDA are I2C serial lines. Pullups\nexists on the SensorStation board. The "CS" pin is a \ngeneric, dedicated GPIO from the Raspberry Pi that can \nbe used to enable the device, work as a chip select, or\nperform a function, such as PWM. Both 3.3V and 5V are\navailable to the accessory and are directly connected to\nthe main power bus. No current limiting, other than the \nmain SensorStation polyfuse, is implemented. For more\ndetails, please see the SensorStation Accessory\ndocumentation.
