Product Details

The MAX31331 shield evaluation kit (EV kit) is a fully assembled and tested PCB to evaluate the MAX31331, an ultra-low power, low-cost, real-time clock (RTC) with I2C interface and power management. The shield operates from a single supply (either from USB or external power supply) and the onboard crystal provides a 32.768 kHz 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 MAX31331 shield EV kit provides the hardware and software graphic user interface (GUI) necessary to evaluate the MAX31331. The kit includes an installed MAX31331. It connects to the PC through a MAX32625 PICO board and a micro-USB cable.
