Analog Devices MAX31343SHLD Shield Evaluation Kit is a fully assembled and tested PCB to evaluate the MAX31343. The MAX31343 is a low-cost, extremely accurate, real-time clock (RTC) with I2C interface and power management. The shield operates from a single supply, either from USB or external power supply. An integrated microelectromechanical systems (MEMS) resonator enhances the long-term accuracy and eliminates the external crystal requirement in the system. This device is accessed through an I2C serial interface provided by a MAX32625 PICO board. The MAX31343 shield provides the hardware and software user interface (GUI) necessary to evaluate the MAX31343. The kit includes a MAX31343EKA+T. It connects to the PC through a MAX32625 PICO board and a micro-USB cable.
