From Prototype to Production with Eagle PCB Design Workshop 3 & 4 PCB Layout: Layout of a single-channel CheerLights Wi-Fi controller Robert Mawrey

Open the Schematic Note (mistake from last class)

Create a Board Click generate switch to board

New Board

Board Case https://www.amazon.com/gp/product/B016PO1CWE/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Adjust Board Size to 1.5”x 0.8”

Group the Parts Together (to avoid free version board size restrictions)

Place the Photon on the bottom layer Select “Mirror an Object” Click on the photon (click on the origin + for the photon) Check to make sure the photon labels are mirrored

Place the Photon at position (0,0) Note that the Photon is mounted on the bottom of the board

Display the Grid (Size 0.05”) View->Grid

Place the rest of the parts on the top of the board in the following locations x (in) y (in) Rotation C1 0.620 0.130 C3 0.180 D2 0.950 0.225 90 U2 0.775 270 J3 0.400 J2 0.850 0.575 J1 1.200 180

Note new Routing Features in Eagle 8.1 Obstacle and Walkaround avoidance makes routing much easier Prior to using load the SeeedStudio dru file into Eagle

Draw your first copper trace

Draw the next trace

Draw the third trace (Making room for a future via)

Draw the forth trace (on the bottom)

Use copper pours to connect the power and ground traces Draw a Polygon with the Bottom layer selected

Draw a second polygon on the Top layer

Name the Bottom polygon GND and the Top polygon 5V

Click Ratsnest Note how the copper (burgundy and blue) fills the top and bottom of the board and connects part to 5V and GND

Note that GND pads on the Top are still not connected to ground

Add a via to connect the top and bottom

Rename the via GND

Copy and paste the via

Connect the pads to the vias
