207 Design Lab Device
Before creating your PCB, it is helpful to create schematics of your components and circuits as well as physical builds.
Create LTspice Schematics of an INA, Notch Filter, and Lowpass Filter
This device is comprised of three circuits. Thus, start by creating the INA, Notch Filter, and Lowpass Filter separately in LTspice. The first image is the schematic for the INA followed by the Notch schematic in the upper right corner and finally the Lowpass in the bottom right corner.
Use EasyEDA Software to Create a Schematic of the Entire Device
Utilize the software EasyEDA to first make a schematic of the device, which means that this schematic is comprised of the INA, Notch filter, and Lowpass filter connected into one large integrated circuit.
Convert the EasyEDA Schematic to a PCB
Utilize the EasyEDA software to convert the EasyEDA schematic into a PCB. Set the boundaries for the copper area for the PCB, which should encompass the entire board. Next, you need to route the components of the PCB. To simplify this process, go to the "Route" tab and click the Auto Route option, which enables the EasyEDA software to utilize the most efficient routes and designs to effectively route your PCB.
After completing this step, you can add other components such as holes. Additionally, you can adjust the copper area, track, pad, etc. if needed for your design.
