Weekly Assignment: Add LED and Button to Hello Serial Board
Designing the hello-serial board from scratch was
a good way to
learn how to use Eagle. The biggest problem
encountered was finding the
correct parts from the extensive libraries.
use nets - these can be linked to bus (eg VCC/GND etc) - this make connecting and routing more simple.
check with desgn rules and electrical rules / change routing from 8 to 16.
place components so traces can be sited - (use ratsnest/auto) - save before auto since cannot undo.
export png files for traces/cutout/ schematic @500dpi
Use roland Modela to fabricate the board - see week5 - and stuff the board.
The files were used to mill the board - which was soldered up with the components:
