Original Design Files
Technical documentation
09/04/2013
These are the original design files the V1 release of the EKG Pre-Amplifier electronics.
EKG-PreAmp.sch is the EAGLE Schematic Capture File (SCH). This is the raw design file that you can use to directly modify the circuit and its function. EKG-PreAmp.pcb is the Printed Circuit Board File (PCB). This file contains the layout information associated with the schematic. If you like the circuit but don't like the component placement, you'll want to directly modify the PCB file. Finally, parts.lbr is the EAGLE parts library file. This file contains all of the information (symbol and footprint) for the components that are used in the EKG Pre-Amplifier. If you like a part you see, you can copy parts from this library for your use.
Just save all three of these files into a new EAGLE project on your own computer to get started.
Remember! The PCB file is no good without it's corresponding SCH file in an EAGLE project. Once you break SCH->PCB concurrency, there's no going back!
