This section gives some examples of how to connect ready-to-use modules available from 
different manufacturers to the STM32F030 Value Line Discovery kit via the prototyping 
board included in the kit.

Software examples, based on the connections described below, are available at 

Mikroelektronika, http://www.mikroe.com, has specified two standard connectors for their 
accessory boards, named mikroBUS™ (http://www.mikroe.com/mikrobus_specs.pdf) and 
IDC10.

MikroBUS™ is a 16-pin connector to connect accessory boards very quickly and easily to a 
microcontroller board through SPI, USART or I

C communications, along with additional 

pins such as Analog Input, PWM and Interrupt.

The set of mikroElektronika boards compatible with mikroBUS™ is called “Click boards”.

IDC10 is a 10-pin connector to connect the general purpose I/O of an MCU to other 
accessory boards.

The tables below are one solution for connecting mikroBUS™ and IDC boards to the 
32F0308DISCOVERY; this solution used in the different examples is available at
