Product Description
CPLD Development Board Designed For ALTERA MAX II Series, Features The EPM1270 Onboard, And Integrates Various Standard Interfaces, Pretty Easy For Peripheral Expansions.
Overview
OpenEPM1270 is a CPLD development board that features the EPM1270 device onboard. It supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with ALTERA MAX II series CPLD devices.
