Problem definition

Engineering team need to prototype the project  before they actually implement.

Team needs some prototyping board or evaluation board to get start up.

This boards helps to develop and test the complete features and all the peripherals of LPC1768 micro controller.

Programming language and programmer

Embedded C In system programming using serial port

Applications

e-Metering Home automation Industrial networking Automobiles

Advantages and disadvantages

Advantages :› Single board can be used for development of Various

applications based on ARM Cortex M3 Architecture.› Low cost and low power controller.

Disadvantages : › Controller is fixed and only we can evaluate LPC 1768

controller from NXP.

conclusion

The board that we have designed is of low cost and it contain many peripheral in it.

Resources system internal LPC1768 are quite perfect and suitable for learning and test the operations.

The board also supports group of customers and engineers who actually want study, test, adapt or apply application by self.
