The Total Phase Aardvark I2C USB to SPI Host Adapter is a perfect tool for every developer. This host adapter is a powerful and efficient tool that can be used by developers as a debugging tool. It works on I2C and SPI bus services and allows developers to connect it with Windows, Mac OS or Linux run computer systems via a fast USB connection. This interface allows users to downstream embedded system environment and transmit serial messages to the computer using SPI or I2C protocols.

The USB interface also provides scheduled updates of this adapter and makes it future-proof that are field-installable. The Total Phase Aardvark is cost-effective and very efficient for companies and organisations that are planning to increase their productivity.

  • Fast USB to I2C/SPI master and slave up to 800 KHz. Low cost and versatile
  • I2C multi-master support for greater flexibility
  • SPI master up to 8 MHz and SPI slave up to 4 MHz
  • GPIO with selectable pins for controlling external devices - great for testing!
  • Free Control Centre Software included with lifetime free updates - a really good investment
  • Compatible with a wide range of specialist bus types (see Specification Tab)
  • Integrates well into custom development solutions
  • Excellent value
  • Quantity discounts available

GPIO - General Purpose I/O

  • I2C and SPI pins can be repurposed for more general use, allowing them to be used for custom signals on target system.
  • GPIO functionality can also be combined with I2C or SPI to interact with your target system.
  • GPIO configuration is cached internally to preserve settings between operational mode

Compatible with Other Interfaces

The Aardvark host adapter can also be used to drive other interface types including:

  • Display Data Channel (DDC)
  • System Management Bus (SMBus)
  • Power Management Bus (PMBus)
  • Smart Battery Bus (SBBus)
  • Intelligent Platform Management Interface (IPMI)
  • Two-Wire Interface (TWI)

Using an USB to I2C Host Interface and I2C Bus Analyser to Prototype Embedded Systems

This video demonstrates how an Aardvark I2C/SPI Host Adapter is used to stimulate an I2C target. The Beagle I2C/SPI bus analyser is used to monitor data being transfered between the host PC and the target.
