## Description

The Adafruit LTC4316 I2C Address Translator solves one of I2C's most frustrating limitations: address conflicts. When two devices share the same fixed I2C address, this chip performs on-the-fly address translation — devices on the output side appear at a different address to the controller on the input side, with no code changes needed on the device itself. The translation works by XOR-ing the device address with a configurable bitmask. Two onboard DIP switches let you flip address bits A4, A5, and A6, giving you four translation options per device. For even more flexibility, a solder pad accepts an XOR_LOW resistor to set the bottom 3 address bits according to the datasheet values. Key Features On-the-Fly Address Translation – Transparently remaps I2C addresses using XOR logic Two DIP Switches – Four address translation options by flipping bits A4, A5, and A6 Optional XOR_LOW Resistor – Solder pad for setting bottom 3 address bits for additional options Transparent to Devices – Connected devices still see their original address; only the controller sees the translated address STEMMA QT / Qwiic – Solderless I2C connectors on both sides (input and output) Ideal For Resolving I2C address conflicts between identical sensors Running multiple copies of fixed-address I2C devices on one bus Expanding I2C sensor networks without multiplexer code overhead Projects where device drivers support configurable addresses Package Contents 1× Adafruit LTC4316 I2C Address Translator (STEMMA QT) Note: This chip does not support clock-stretching devices (e.g. BNO055). The translation address is set at boot — if you change DIP switches or resistor values, toggle the Enable pin or power cycle the board. Ensure your device driver supports changing the I2C address to the new translated value. STEMMA QT cable not included.
