week 6. Electronics design

This Week i made some changes on the design from Week 2

In our group assignment, we showed how to use an oscilloscope and a Multimeter. I was responsible for the Setup and to explain the oscilloscope to my Group

PCB V1

In the following videos you can see how i made V2 of my PCB for the MechaDungeon

Prepwork

  1. Creating a new project in a location of your desire
  2. Open the schematic
  3. Realize, that you forgot the librarys
  4. add the XiaoBoard Symbols and Footprint as project librarys
  5. Open the schematic again
  6. place the Xiao Symbol(open the symbol adding prompt by pressing "a" on the keyboard)
  7. Change the Footprint of the Xiao symbol to the correct Footprint by double clicking the symbol of the Xiao and selecting the correct Footprint
  8. Switching to the Board-editor
  9. load the changes from the Schematic-editor to the board

V2

After Designing V1 i realized, that i need more pins because i need more actuators. I changed my MCU from a Xiao Board to an Raspberry Pi Pico 2 W and added Stepper driver boards and a relay aswell as an 5V Converter. For that i needed to create 2 Footprints and Symbols on my own. One for the BTT TMC2209 Stepper Driver and one for the used Relay

Designing Symbols and Footprints

Designing is easy. I just copied the Symbol and Footprint out of the datasheets of the parts i using. In the Video i show you how to make symbol and footprnt for the relay. I did the same already with the Stepper Driver

  1. Open the Symbol editor
  2. Create a new Library and select the place where to save
  3. Create a new Symbol in the library
  4. Place Pins, Text and the Outline of the Symbol
  5. Save the Symbol
  6. Open the Footprint editor
  7. Create a new Library and select the place where to save
  8. Create a new footprint in the library
  9. Place Pins, Text and the Outline of the Symbol
  10. Save the Footprint
  11. Go back to the Symbol
  12. Edit standard footprint of your symbol to the newly created footprint
  13. Enjoy your library
