MAX31343 Shield

Procedure

The shield is fully assembled and tested. 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.

6) Open the MAX31343 RTC SHIELD Software, shown

in Figure 2.
