5 Connecting modules on the prototyping board
This section gives some examples of how to connect ready-to-use modules available from
different manufacturers to the STM32F0DISCOVERY kit via the prototyping board included
in the kit.
Software examples, based on the connections described below, are available at

5.1 Mikroelektronica accessory boards
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 acce
ssory boards very quickly and easily to a
microcontroller board through SPI, USART or I2C communications, along with additional
pins such as Analog Input, PWM and Interrupt.
The set of mikroElektronika boards compatib
le with mikroBUS™ is called “Click boards”.
IDC10 is a 10-pin connector to connect the general purpose I/O of an MCU to other
ac
cessory boards.
The tables below are one solution for connecting mikroBUS™ and IDC boards to the
STM32F0DISCOVERY; this solution used in th
e different examples is available at
