The AMD Kria™ KV260 Vision AI Starter Kit requires a 12V, 3A power supply adapter to power the kit.
Note: The power supply adapter is not included in the KV260 Starter Kit. The following table lists the suggested power supply adapter that must be purchased separately.
Table 1. Power Adapters to Purchase for the KV260 Starter Kit
Vendor Model Description
CUI Inc. SMI36-12-V-P6 +12V, 3A DC adapter using a center-pin positive barrel connector (2.5 mm ID, 5.5 mm OD)

The power supply adapter barrel connector plugs into the DC jack (J12) to supply the +12V power source to KV260 Starter Kit.

Powering the K26 SOM

  • The KV260 Starter Kit carrier card on-board regulator generates a 5V supply and provides power to other voltage regulators.
  • The SOM power rail (VCC_SOM) is powered by the 5V supply.
  • Next, the SOM on-board power-on sequencing starts.
  • The carrier card provides the programmable logic (PL) the VCCO voltage rails after the SOM asserts the VCCOEN_S_M2C and VCCOEN_PL_M2C signals

Power Telemetry

A power monitor device is available on the SOM power rail (VCC_SOM). You can access the total power consumed by the SOM module through the I2C bus and AMD provided utilities.

Powering Peripherals

The KV260 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 KV260 Starter Kit carrier card. 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 individual 900 mA power switches per port.
Note: The total current (across all four ports) is allocated at 2.1A.

Pmod Connector

The Pmod interface (from Digilent Inc.) is supported by the 3.3V, 100 mA capacity on the supply pin.

Raspberry Pi Camera Interface

The Raspberry Pi camera 15 pin interface connector is supported by the 3.3V supply voltage on the supply pin.

IAS Module Connector

The SOM supports two IAS module connectors, as defined by the ON Semiconductor IAS module definition standard. The KV260 Starter Kit carrier card provides 2.75V, 1.8V, and 1.2V supply rails on specified power pins.
