A breadboard friendly breakout for the Linear Technology LTC4311 I2C/SMBus Accelerator.
This "bus accelerator" is an active bus terminator. Bus performance is improved greatly compared to using pull-up resistors alone. The active terminator allows for a longer, higher capacitance I2C bus and improves noise immunity. In heavily loaded systems multiple active terminators may be used to improve performance further.
The LTC4311 is a dual terminator and attaches to the SCK and SDA bus lines. It works in 5V and 3.3V designs.
This breakout module does not allow for disabling the LTC4311.
The LTC4311 is a tiny SMT part, plus they're relatively expensive. This breakout board makes it easy to use, and it's the cheapest breakout available. Every maker that works with I2C bus should have one of these in their toolkit.
