Evaluates: MAX31343 MAX31343 Shield General Description Shield Contents The MAX31343 shield is a fully assembled and tested Assembled MAX32625 PICO controller board PCB to evaluate the MAX31343, low-cost, extremely Micro USB cable 2 accurate, real-time clock (RTC) with an I C interface and power management. The shield operates from a Assembled circuit board including MAX31343EKA+T single supply, either from a USB or external power sup- ply, and the integrated microelectromechanical systems Quick Start (MEMS) resonator enhances the long-term accuracy and eliminates the external crystal requirement in the system. Required Equipment 2 This device is accessed through an I C serial interface One pico ammeter for measuring the current provided by a MAX32625 PICO board. One oscilloscope and one oscilloscope probe The MAX31343 shield provides the hardware and soft- ware user interface (GUI) necessary to evaluate the One PC or laptop with Microsoft Windows 7 or later MAX31343. The shield includes a MAX31343EKA+T. It One USB A male to Micro-B male cable connects to the PC through a MAX32625 PICO board and a Micro USB cable.

Use the follow- ing steps to verify board operation. 1) Place the MAX31343 shield on a nonconductive sur- face to ensure that nothing on the PCB gets shorted to the workspace. 2) Verify that all jumpers are in their default position as shown in Table 1. 3) Connect the MAX32625 PICO board to the shield at the location shown as MAX32625 PICO (Figure 1). 4) Connect the USB Type A male to Micro-B male cable between the MAX32625 PICO board and PC/laptop. 5) Go to the MAX31343 shield product page to download and install the latest version of the MAX31343 RTC SHIELD Software. Figure 1. Connection and Setup 6) Open the MAX31343 RTC SHIELD Software, shown in Figure 2. Table 1.
