This is for them who really want to learn FPGA (Field Programmable Gate Array), we are providing path to them. There is immense demand of FPGA based system, the trainers are quite expensive and sometime does not meet our requirement. So, I thought that a very low cost FPGA based trainer which would help our juniors and other engineers to get a custom with FPGA. The FPGA available in our market was chosen , it’s a raw board .The most of the thing that student and engineers would require is interfacing as we have mention above and the best thing is ,it can be a excellent source for the engineers trying to develop their own hardware where cost constrain are manageable .
