The DE1 is an excellent solution all levels of users:

• For simple experiments, the DE1 board includes a sufficient number of robust switches (of both toggle and push-button type), LEDs, and 7-segment displays.

• For more advanced experiments, the user can utilize the SRAM, SDRAM and Flash memory IC.  

• For experiments that require a processor and simple I/O interfaces, it is easy to instantiate Altera’s Nios II processor and use interface standards such as RS-232 and PS/2.

• For experiments that involve multimedia the DE1 equipped with standard connectors for microphone, line-in, line-out (24-bit audio CODEC), SD memory card connector and VGA; these features can be used to create CD-quality audio applications and video.

• The DE1 board includes two expansion headers which enable the user to connect other user defined boards. 
  
  

DE1 board provides users many features to enable various multimedia project development.

Component selection was made according to the most popular design in volume production multimedia products.

The DE1 platform allows users to quickly understand all the insight tricks to design projects for industry.
