MAX31343 Shield Software User Guide
This document provides the necessary information to program and evaluate the MAX31343 realtime clock (RTC) on the MAX31343 shield board using the provided graphical user interface (GUI) software. The MAX31343 shield is a fully assembled and tested PCB to evaluate the MAX31343, a lowcost, extremely accurate, real-time clock with an I2C interface. The shield operates from a single supply, either from USB or external power supply, and the integrated micro-electromechanical systems (MEMS) resonator enhances long-term accuracy and eliminates the external crystal requirement in the system. This device is accessed through an I2C serial interface provided by the MAX32625PICO board.
