The Linker kit allows the use of the Raspberry Pi board without complicated soldering. Each component is presoldered to a miniature PCB. Jumper cables are provided to connect all the various components.
Note the Slide Potentiometer, Touch Sensor and Temperature modules require the use of the MCP3008 Analog to Digital converter processor to function.
Halherta has a great instruction set for setting this up over at Hertaville Interfacing an SPI ADC (MCP3008) chip to the Raspberry Pi
This kit also works great with the PCDuino board as well without requiring the ADC chip.
