General Description
The MAX31334 shield evaluation kit (EV kit) is a fully assembled and tested PCB to evaluate the MAX31334, an ultra-low power, low-cost, real-time clock (RTC) with
integrated power switch, I2C interface, and power management. The shield EV kit operates from a single supply (either from USB or external power supply) and the onboard crystal provides a 32.768kHz clock signal. This device is accessed through an I2C serial interface provided by a MAX32625PICO board connected to a PC by a USB port.
The MAX31334 shield EV kit provides the hardware and software graphic user interface (GUI) necessary to evaluate the MAX31334. The kit includes an installed MAX31334. It connects to the PC through a MAX32625 PICO board and a micro-USB cable.
