Electronic Design


Circuit board production

The assignment for this week is to produce the serial echo and add a few devices onto the board. This required that we redesign the schematic and circuit using eagle or any other CAD software.


Schematic capture

This required the use of eagle but I opted to use proteus Labcenter software because I have used it for a while. The schematic is straight forward to use and the schematic is as following below.



circuit board and components

After designing the schematic. The software generates netlists for the components. This helps in maintaining the connection that have been specified in the schematic. Every time a component is placed, a list of all components is reduced so that one will be sure to have placed all the components on the circuit board. The circuit board will be using surface mount devices and the track will be made of top copper. The details are as below.

cutting the board

once the circuit design is ready, the next process is to produce the BMP image or the png and send to the roland for cutting
