3.5.2 mikroBUS Interface
The SAMA5D2-ICP hosts three pairs of 8-pin female headers (J21, J22, J23) for the mikroBUS interfaces. The
mikroBUS defines mainboard sockets and add-on boards used for interfacing microprocessors with integrated
modules with proprietary pin configuration and silkscreen markings. The pinout consists of three groups of
communication pins (SPI, UART and TWI), four additional pins (PWM, interrupt, analog input and reset) and two
power groups (+3.3V and GND on the left, and 5V and GND on the right 1x8 header).
The figures below illustrates the implementation of the mikroBUS interfaces.
