MAX7327 Evaluation Kit/Evaluation System (MAX7327EVKIT) (MAX7327EVKIT)

The MAX7327 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the capabilities of the MAX7327 I²C port expander with 12 push-pull outputs and 4 open-drain I/O ports. The MAX7327 EV kit also includes Windows® 98SE/2000/XP-compatible software, which provides a simple graphical user interface (GUI) for exercising the MAX7327's features.

The MAX7327 evaluation system (EV system) includes a MAX7327 EV kit and a Maxim CMAXQUSB serial interface board.

The CMAXQUSB board connects to a PC's USB port and allows the transfer of I²C commands to the MAX7327 EV kit.

The EV kit comes with the MAX7327ATG+ installed. The MAX7327 EV kit can also be used to evaluate the MAX7324/MAX7325/MAX7326. Contact the factory for free samples of the pin-compatible MAX7324ATG+/MAX7325ATG+/MAX7326ATG+ to evaluate these parts.
