1 Designing the PCB

Learn It

  • Although the circuit you've designed should be fine, we need to make a few changes before we design a PCB
  • Firstly we want to use a 9V supply (as they're cheaper), so we'll need a voltage regulator.
  • Modify your circuit so you use the setup below to provide power.

  • Check with your teacher that your circuit is correct before proceeding.

Try It

  • You're now going to design your own PCB.
  • Initially you just need to follow this guide.
  • Click on this button to begin the PCB Wizard

  • Choose Single Sided/Thin Tracks and check the box to allow customisation of the board.

  • The default size of the board will be fine

  • As will the default components

  • And we need to use small pads

  • Lastly uncheck the box, so that we can place components ourselves.

  • Click convert and you should have something that looks a little like this.

Badge It

  • It's now up to you to try and create the PCB.
  • You'll be awarded your badge depending on the size and neatness of your finished design.
  • A silver badge will be awarded if you create a viable PCB of any size, without using jump wires.
  • A gold badge will be awarded if you create a viable PCB no larger than 100mm by 100mm, without using jump wires.
  • A platinum badge will be awarded if you create a viable PCB no larger than 50mm by 50mm, without using jump wires.
