USB-SPI Adapters with configurable frequency (up to 48MHz), clock phase and polarity. SPI master, slave and SPI Flash Interfaces.

The Aardvark™ I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter. It allows developers to interface a Windows, Linux, or Mac OS X PC via USB to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols.

USB To UART/I2C/SPI/JTAG Converter Board with Aluminum Alloy Case, Aceess to Control Various UART/ I2C/SPI/JTAG Devices via Computer, Support Win7/8/8.1/10/11, Linux, etc. Compatible with 3.3V and 5V

Use the Adafruit FT232H USB to GPIO / SPI / I2C breakout with Adafruit's SPI & I2C devices. Native GPIO bit twiddling your way to success. they're a dime a dozen. Lets use them!

The FT4222HQ is a High/Full Speed USB2.0-to-Quad SPI/I2C device controller in a compact 32-pin QFN package. The device requires an external crystal at 12MHz in order for the internal PLL to operate.

USB to SPI and I2C adapter as USB plug.
