EVAL-CN0564-ARDZ

EVAL-CN0564-ARDZ is a printed circuit board that solves the problem of long distance, robust, SPI/I2C communication simply and easily without any sacrifices to circuit component count, operating speed, or software complexity. Ideal operation in high noise, harsh industrial environments require tolerance to large ground potential differences. The SPI/ I2C extenders feature robust transceivers which operate over an extended common mode range of ±25V (for SPI communication) and ±15V (for I2C communication) for distances up to 1200m. Each link consists of a single device at either end of the cable, capable of being powered from 3V to 5.5V, while a separate logic supply allows the I2C or SPI interface to operate from 1.62V to 5.5V. It has Arduino headers for easy evaluation and integration of its SPI and I2C extenders with the widely available Arduino UNO and other Arduino compatible devices.

• Uses LTC4331 and LTC4332 to extend I2C/SPI signals up to 1200m
