The USB-ISS module is an enhanced version of our low cost USB-I2C module, offering additional functionality at the same low price. Communication to I2C, SPI and serial buses as well as digital I/O control and analog inputs.

Extra features over the USB-I2C are:
Support I2C at 20khz-1mhz
I2C + I/O
SPI mode
Serial mode (polled port)
I2C direct - build your own I2C sequence from discrete functions like I2C start
Bootloader - any future updates can be added 
3.3v operation
Mounting holes on PCB
