Easier connectivity and simple conguration 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 PRO
™
v7 is a development board which supports mikroBUS
™
with three
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.
