Footnotes

1. Projects from a tutorial are 100% fine! We just want to ask so we can count how people are using tutorials. ↩

2. OnBoard Live is a special version of OnBoard where you can earn more money for designing advanced boards. Check out the #onboard-live channel on our Slack! ↩

3. Trick or Trace is a limited time design contest for PCBs, enter your PCB into one of the three catagories and by peer voting, get chosen for a 100$ additional grant from OnBoard. ↩
