I just finished designing my first project for fabrication, and I was wondering if anyone would mind looking over my project to see any possible errors.
Major issues I am worried about:
- Traces too small
- Traces connecting to the wrong thing, risking shorts
- stuff too close together
- Anything that catches you eye that could result in a failure to have the board work.
There are two boards in this project. One is a control board that uses an ATMega328 to read data from a bluetooth reciever and then trigger pulsing signals on the MCP23017 port expanders.
The other board recieves signals from the port expander and transfers them to LEDs.
To make things simpler, I am linking to GerbLook.
Note that the one labeld Control Board no expansion header is outdated, and does not need to be checked.
