mikroBUS
™
sockets
The superior connectivity features of the Fusion for STM32 v8 development board are
rounded up with five standardized mikroBUS
™
host connectors. It is a considerable
upgrade for the board, as it allows interfacing with the vast amount of Click boards
™
.
mikroBUS
™
is the add-on board standard that offers maximum expandability with the
smallest number of pins. More information at www.mikroe.com/mikrobus
All the mikroBUS
™
sockets are now redesigned and improved. They became much
sturdier, allowing a better grip of the Click board
™
. In addition to added horizontal
supports between two 8-pin connectors, the right lower edge is chamfered at the
angle of 45°, the same as the Click board
™
, making it seamlessly fit into the mikroBUS
™
socket. The new mikroBUS
™
socket is now a fully-fledged, standardized monolithic
component with all its pins clearly labeled, offering very good grip for the Click board
™
,
preventing it to flip over or to be placed incorrectly.
The mikroBUS
™
socket supports the following communication interfaces: SPI, UART,
and I2C. There are also single pins reserved for PWM, Interrupt, Analog input, Reset,
and SPI Chip Select. The mikroBUS
™
socket also contains pins with the two power rails
(3.3V and 5V), along with the GND pins.
Each MCU card has different pins routed to the mikroBUS
™
sockets, depending on
the particular MCU. Therefore, each mikroBUS
™
socket is labeled on the development
board with its ordinal number, by which the connector is referenced to in the Mikroe
development environment, software applications, tutorials, etc.
Also, each MCU card has the pins routed to the corresponding mikroBUS
™
clearly
labeled on the MCU card itself, as described in the MCU CARDS section. This allows users
to instantly know which MCU pin is routed to a pin on the specific mikroBUS
™
socket.
