TWI Adapter Card

This card serves several purposes. It provides ease of connectivity to to all kind of I2C capable devices. Usually TWI/I2C is used as a configuration interface for a attached devices, or for user interfaces. Such as Keypads, LEDs, Buttons, Touchscreens, Display Devices, etc.

The Bus length formed by Adaptor Card can exceed several inches, because only required signals are connected to the bus. The card provides 3.3 Volt and 5 Volt supply, as well as two sets of 3.3V and 5 Volt I2C signals, namely SDA (Data), SCL (Clock)

In addition 3 other Blackfin General Purpose IOs can be connected to the TWI/I2C Adaptor connector, unused signal - maybe used by other a High-Speed devices on-board or by other Blackfin STAMP adaptor cards are not extended - signal integrity issues are therefore less likely to happen.
