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 STM32F030 Value Line Discovery kit via the prototyping
board included in the kit.
Software examples, based on the connections described below, are available at
www.st.com/stm32f0-discovery.
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 accessory boards very quickly and easily to a
microcontroller board through SPI, USART or I
2
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
www.st.com/stm32f0-discovery.
