pinout explained
Easier connectivity and simple configuration
are imperative in modern electronic devices.
Success of the USB standard comes from it’s
simplicity of usage and high and reliable data
transfer rates. As we in MikroElektronika see it,
Plug-and-Play devices with minimum settings
are the future in embedded world too. This is
why our engineers have come up with a simple,
but brilliant pinout with lines that most of
today’s accessory boards require, which almost
completely eliminates the need of additional
hardware settings. We called this new standard
the mikroBUS
™
. EasyPIC
™
v7 for dsPIC30
®
supports mikroBUS
™
with two on-board
sockets. As you can see, there are no additional
DIP switches, or jumper selections. Everything
is already routed to the most appropriate pins
of the microcontroller sockets.
mikroBUS

host connector
Each mikroBUS
™
host connector consists of two
1x8 female headers containing pins that are
most likely to be used in the target accessory
board. There are three groups of communication
pins: SPI, UART and I
2
C communication. There
are also single pins for PWM, Interrupt,
Analog input, Reset and Chip Select. Pinout
contains two power groups: +5V and GND on
one header and +3.3V and GND on the other
1x8 header.
