When placing resistors on the schematics, make sure you select the appropriate footprint! (1206 OR 1210, check the list)

n ohm resistors, package 1210 or 1206 don't use 0633

The lab has 10R and 120R resistors.

Schematic & Footprint

This is how you obtain the schematic+footprint for the resistors.

  1. Open the altium content vault. If you don't know what that is, check out this page.
  2. In the "Vault Folders" panel in the "Vaults" window that appears, expand the "Unified Components" folder.
  3. Expand "Components - Generic".
  4. Expand "Resistors".
  5. Expand "Basic Surface Mount"
  6. Select "1210" OR "1206" (check the table and the resistor you are placing!)
  7. Select & Place one of the resistors that appear in the top-left panel.

Note that since we are soldering on the resistors ourselves, it doesn't really matter which resistor you select as long as it's one of these. They're all the same size and have the same footprint, y'see. Just make sure you name the resistor appropriately so that it is possible to see what its resistance is supposed to be.

Capacitors

Value Package farnell comment count
10µF Elec cap Farnell size B pol cap footprint, used in the PSU schematic 4
0.1µF 1210 Farnell PSU 13; crystal 2 15
0.1µF Elec cap farnell Serial Port Driver, size B pol cap footprint created 5
1µF 1210 Farnell 50 for decoupling, 3 used in the microcontroller schematic 53
4.7µF 1210 Farnell used in the microcontroller schematic 1

The lab has 0.1uF/100nF 1206 SMD capacitors.

Schematic & Footprint

For the 0.1µF 1210 Capacitor

  1. Open the altium content vault. If you don't know what that is, check out this page.
  2. In the "Vault Folders" panel in the "Vaults" window that appears, expand the "Unified Components" folder.
  3. Expand "Components - Generic".
  4. Expand "Capacitors".
  5. Expand "Basic Surface Mount"
  6. Expand "1210 (3225 Metric)"
  7. Select "100 V"
  8. Select & place one of the capacitors that appear in the top-left panel.

For the 10µF Capacitor

???? Working on it, yo.
