ST MEMS "adapter boards", standard DIL24 socket

STMicroelectronics has defined a standard DIL24 connector to easily evaluate its MEMS
sensors connected to a microcontroller through SPI or I2C communications.
Table 9 is one solution for connecting the DIL24 boards to the STM32F0DISCOVERY, this
solution is used in different examples and available at www.st.com/stm32f0discovery.
