The MAX7325 evaluation kit (EV kit) is a fully assembled
and tested printed-circuit board (PCB) that demon-
strates the capabilities of the MAX7325 I
expander with eight push-pull outputs and eight open-
drain I/Os. The MAX7325 EV kit also includes
Windows
vides a simple graphical user interface (GUI) for exer-
cising the MAX7325’s features.
The MAX7325 evaluation system (EV system) includes
a MAX7325 EV kit and a Maxim CMAXQUSB serial-
interface board. The CMAXQUSB board connects to a
PC’s USB port and allows the transfer of I
to the MAX7325 EV kit.
The EV kit comes with the MAX7325ATG+ installed.
