Based on the ATMega328(P) µC, the project code is hosted here: [login to view URL]). What I need from you: - Use EagleCAD - I created the files using this program. - Download and open the project hardware files from here: [login to view URL] - or from the attached zip file. If you don't have the libraries required, I can share them with you. There are a few parts I want to swap out (I will provide the part numbers and datasheets), the schematic and board layout don't have those parts implemented yet - but they are pin compatible. I need you to look over the design and suggest fixes/improvements on any issues that can be prevented (e.g.; a gnd pin connection where it is not supposed to be, etc). I don't need you to redesign or populate the board with the parts I will be using - I simply need to know if I have introduced mistakes into the design.

Hi, the swapping ICs are nice although ULN2003A is a bit cheaper. Whats the max voltage IN at the 7805 side? My bid actually includes redesigning of the board as it seems it can be made little smaller (if needed) and also the component plan could be changed a bit for the best routing of the traces. There are some traces which need to be thicker than what has been used so that it can carry more current without producing heat and copper loss can be minimized. It would be an interesting job. I mentioned 5 days time just to surf the net in case if cheaper component can be found while maintaining the system performances. Lets get started. Thanks and I am looking forward to hear from you. Regards... Roy

Hello, I have several hints regarding schematic design. Also there are even more things to suggest for PCB design. I would also look into the chips datasheets to follow manufacturers recommendations. Looks like a hour or two and you should have a good design. All the best!
