To complete this workshop, you will need:
- Eagle Software, part of the Autodesk Suite
- A Mouse connected to your computer
You should have previously worked through the CASA0016 Week 7 workshop available here:
You task is to design a plant monitor PCB similar to the one used in CASA0-0014. Here is the circuit diagram for this simplified plant monitor.
I have set up an initial project for you that includes a schematic containing the relevant parts you will need (see below).
I have also created a board layout sized for Feather Huzzah, with the header holes correctly postioned (see below).
Your task is to
- First connect up the schematic to reflect the arrangement shown in the circuit diagram above. Once you have done this, run an Electrical Rule Check (ERC) to check there are no errors. If there are errors you will need to fix them.
- Once you have no errors move to the board layout and position the parts appropriately. You should not change the dimensions of the board or the position of the headers on the board. When you have positioned the parts to your satisfaction run the autorouter tool to route the PCB tracks. You should run a Design Rules Check (DRC) to check there are no errors.
- Finally, generate the Gerber files suitable for PCB fabrication. You need to run the CAM Processor on the board layout (File -> CAM Processor) choosing a suitable template such as from System Examples -> Third Party -> OSH Park or Seeed Fusion, selecting the _2_layer.cam option. You should be able to view the generated Gerber files in a suitable Gerber viewer (e.g. https://www.pcbway.com/project/OnlineGerberViewer.html)
As an optional exercise, if you have time to spare you could try creating a silk screen for your board.
