Adafruit LTC4311 I2C Extender / Active Terminator - STEMMA QT / Qwiic Pi 400 Kit allowing you to control 5VI2C is designed for short distance communication on a PCB, but extending it over long cables introduces capacitance and resistance that can slow down signals. The Adafruit LTC4311 active terminator solves this by boosting the I2C bus rise times, enabling much faster data rates over long cables without complex hardware changes. The LTC4311 is easy to usesimply connect it to your I2C bus (usually at the start of the chain). It automatically detects
