The USB I2C/IO interface board provides a simple, "drop-in", solution for customers that need to connect hardware to a P.C. The board provides 20 bits of user-configurable digital I/O, and an I2C interface..
The full-speed USB interface provides your application hardware with a "Hot Plug and Play", 12Mbps, industry standard connection to your P.C. host.
Please reference the schematic file for hardware details.
The included device driver, dll, and example application software make it easier than ever to access your hardware from your P.C.
The software provides support for connection of multiple boards. This makes the USB I2C/IO a great solution when multiple equipment instances are required (test fixtures, production equipment, instruments, etc.).
The board can be configured to download it's firmware upon connection to the P.C., or to boot from the I2C bus. An onboard I2C eeprom is included on the board, providing 16KB of storage for code or data.
