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

www.st.com/stm32f0discovery.

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 accessory 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 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

STM32F0DISCOVERY; this solution used in the different examples is available at

www.st.com/stm32f0discovery.
