Summary
The Xilinx® Kria™ KR260 Robotics Starter Kit is comprised of a non-production
version of the K26 system-on-module (SOM), carrier card, and thermal solution. The
SOM integrates core digital hardware components including a Zynq® UltraScale+™
MPSoC, run-time memory, non-volatile boot devices, an integrated power solution,
and a security module. The robotic-focused carrier card provides various
application peripheral options including a sensor input, video display outputs, USB,
SD card, Raspberry Pi HAT interface, Pmod headers, SFP+ connector, and Ethernet
physical interfaces. The thermal solution includes a heat sink, heat sink cover, and
fan. The Kria KR260 Robotics Starter Kit is designed to provide customers a
platform to evaluate their target applications and ultimately design their own carrier
card with K26 SOMs. Key target robotics applications are supported with an
emphasis on industrial and automation markets.

Interfaces
The following figure and table provide an overview of the physical connections, their
designators, and relative position on the starter kit. The table uses the following
abbreviations to indicate if a specific designator is located on the carrier card or on
the SOM.
CC = Device or interface is located on the carrier card
SOM = Device or interface is located on the SOM
On the carrier card, there are four USB ports. USB0 and USB1 are each connected to
a pair or USB physical port interfaces. There are four Ethernet interfaces with one
pair connected to PS GEMs and one pair to PL-based GEMs. As shown in the
following figure, GEM1 on J10C is the default firmware and software Ethernet
interface used for the image recovery application and the primary Ethernet interface
in Linux.

Initial Setup
Powering the Starter Kit and Power Budgets
The Kria™ KR260 Robotics Starter Kit requires a 12V, 3A power supply adapter to
power the kit. The adapter is included in the kit. The power supply adapter barrel
connector plugs into the DC jack (J12) to supply the +12V power source to KR260
Starter Kit.
Powering the K26 SOM
1. The KR260 Starter Kit carrier card on-board regulator generates a 5V supply
and provides power to other voltage regulators.
2. The SOM power rail (VCC_SOM) is powered by the 5V supply.
3. Next, the SOM on-board power-on sequencing starts.
4. The carrier card provides the programmable logic (PL) the VCCO voltage rails
after the SOM asserts the VCCOEN_PS_M2C and VCCOEN_PL_M2C signals.
Power Telemetry
A power monitor device is available on the SOM power rail (SOM_5V0). You can
access the total power consumed by the SOM module through the I2C bus and
Xilinx provided utilities.
Powering Peripherals
The KR260 Starter Kit carrier card supplies power to the I/O peripherals as specified
by the following interface specifications.
USB3.0

✎
There are four USB3.0 interface ports available on the KR260 Starter Kit carrier
card. There are two independent USB controllers, but they share a power source.
Each port can deliver a 5V supply to the attached I/O peripherals with up to 900 mA
per port. All ports are protected against an over-current event through 1.0A power
switches per pair.
Note: The total current (across all four ports) is allocated at 2.0A.
Pmod Connector
The 12-pin Pmod interface (from Digilent Inc.) is specified to be 3.3V, 100 mA. The
four ports are supported by a 3.3V, 1.0A shared capacity across all connectors.
Raspberry Pi Expansion Header
The Raspberry Pi expansion header is for use with Raspberry Pi HATs. This 40-pin
interface connector is supported by 3.3V and 5.0V supply voltages. There is a 1.0A
limit per voltage rail.
SFP+
Pluggable SPF+ transceiver modules are supported by the SFP+ cage that provides
a 3.3V, 600 mA supply budget.The total power consumed must fall within the
power budget for the SPF+ module. The SFP+ power is not explicitly limited, thus
care must be taken when attaching optional accessories to your carrier card.
Framos FPA SLVS-EC
The Framos FPA SLVS-EC connector is supported with two voltages. The carrier
provides 1.8V at 800 mA and 3.8V with a limit of 1.0A. Because the 1.8V is not
explicitly limited, care must be taken when attaching accessories to ensure a
proper power budget.
microSD Card
The microSD card is supported by the 3.3V supply voltage with a power budget of
200 mA. This should be more than adequate for standard cards. It is also not
explicitly limited. The starter kit supports up to 64 GB microSD cards.
