Board feature Processor feature used Description

UART Two DUART modules (DUART1 and

DUART2), each containing two

UARTs

DUART1:

• UART1 is routed to USB-UART bridge and supports USB

port to access the serial port as console, requires a

jumper to be placed on a header

• UART1 can be used without flow control on an expansion

header, requires the jumper to be removed from the

header

• UART3 can be used to interface with a click board

plugged-in into mikroBUS socket

DUART2:

• UART2 can be used with/without flow control on an

expansion header

• UART4 can be used on the same expansion header

SPI

One serial peripheral interface (SPI)

• Connects to a click board plugged-in into mikroBUS

socket using PCS0 (3.3 V)

• Supports SPI expansion header using PCS[1:3] (3.3 V)

I2C Three I2C controllers (I2C1, I2C3,

and I2C4)

• I2C1: Controls all system devices and can be accessed

remotely through an I2C expansion header (I2C1)

• I2C3: Can be accessed remotely through an I2C

expansion header (I2C3)

• I2C4: Can be accessed remotely through an I2C

expansion header (I2C4)
