    pincount: 4
  X2:
    pincount: 4

cables:
  W1:

    length: 1

connections:
  -
    - X1: [1-4]
    - W1: [1-4]

2 - Adding parameters and colors

  • Parameters for connectors and cables
  • Auto-calculate equivalent AWG from mm2
  • Non-sequential wiring

Source:

connectors:
  X1:
    pincount: 4
    # More connector parameters:
    type: Molex KK 254
    subtype: female
  X2:
    pincount: 4
    type: Molex KK 254
    subtype: female

cables:
  W1:
    wirecount: 4
    # more cable parameters:
    length: 1
    gauge: 0.25 mm2
    show_equiv: true # auto-calculate AWG equivalent
    colors: [WH, BN, GN, YE]

connections:
  -
    - X1: [1-4]
    - W1: [1-4]
    # non-sequential wiring:
    - X2: [1,2,4,3]

3 - Pinouts, shielding, templates (I)

  • Connector pinouts
    • Pincount implicit in pinout
  • Cable color codes
  • Cable shielding, shield wiring
  • Templates

Source:

connectors:
  X1: &template1 # define a template for later use
    pinout: [GND, VCC, RX, TX] # pincount implicit in pinout
    type: Molex KK 254
    subtype: female
  X2:
    <<: *template1 # reuse template

cables:
  W1:
    wirecount: 4
    length: 1
    gauge: 0.25 mm2
    show_equiv: true
    color_code: DIN # auto-assign colors based on DIN 47100
    shield: true # add cable shielding

connections:
  -
    - X1: [1-4]
    - W1: [1-4]
    - X2: [1,2,4,3]
  - # connect the shielding to a pin
    - X1: 1
    - W1: s

4 - Templates (II), notes, American standards, daisy chaining (I)

  • Overriding template parameters
  • Add nodes to connectors and cables
  • American standards: AWG gauge and IEC colors
  • Linear daisy-chain
    • Convenient for shorter chains

Source:

connectors:
  X1: &template_con
    pinout: [GND, VCC, SCL, SDA]
    type: Molex KK 254
    subtype: male
    notes: to microcontroller # add notes
  X2:
    <<: *template_con # use template
    subtype: female   # but override certain parameters
    notes: to accelerometer
  X3:
    <<: *template_con
    subtype: female
    notes: to temperature sensor

cables:
  W1: &template_cbl
    wirecount: 4
    length: 0.3
    gauge: 24 AWG # specify gauge in AWG directly
    color_code: IEC # IEC 62 colors also supported
    notes: This cable is a bit longer
  W2:
    <<: *template_cbl
    length: 0.1
    notes: This cable is a bit shorter

connections:
  -
    - X1: [1-4]
    - W1: [1-4]
    - X2: [1-4]
  - # daisy chain connectors (in line)
    - X2: [1-4]
    - W2: [1-4]
    - X3: [1-4]

5 - Ferrules, wire bundles, custom wire colors

  • Ferrules
    • Simpler than connectors
    • Compact graphical representation
    • Only one pin, only one connection, no designator
    • Define once, auto-generate where needed
  • Wire bundles
    • Internally treated as cables
    • Different treatment in BOM: Each wire is listed individually
    • Represented with dashed outline
  • Custom wire colors
    • Wirecount can be implicit in color list

Source:

connectors:
  X1:
    pinout: [+12V, GND, GND, +5V]
    type: Molex 8981
    subtype: female

ferrules: # ferrules
  F1:
    type: Ferrule, crimp
    subtype: 0.5 mm²
    color: OG # optional color

cables:
  W1:
    category: bundle # bundle
    length: 0.3
    gauge: 0.5 mm2
    colors: [YE, BK, BK, RD] # custom colors, wirecount is implicit

connections:
  - # attach ferrules
    - F1 # no need for list of connections; one ferrule per wire is auto-generated and attached
    - W1: [1-4] # a new ferrule is auto-generated for each wire
  - # attach connectors (separetely from ferrules)
    - W1: [1-4]
    - X1: [1-4]

6 - Custom ferrules

  • Custom ferrules
    • Allows attaching more than one wire to a ferrule
    • Requires defining them as regular connectors with unique designators, adding category: ferrule parameter

Source:

connectors:
  X1:
    pinout: [+12V, GND, GND, +5V]
    type: Molex 8981
    subtype: female
  F_10_1: # manually define a ferrule (with unique designator)
    category: ferrule
    type: Ferrule, crimp
    subtype: 1.0 mm²
    color: YE

ferrules: # ferrules
  F_05:
    type: Ferrule, crimp
    subtype: 0.5 mm²
    color: OG # optional color

cables:
  W1:
    category: bundle # budnle
    length: 0.3
    gauge: 0.5 mm2
    colors: [YE, BK, BK, RD] # custom colors, wirecount is implicit

connections:
  - # attach ferrules
    - F_05
    - W1: [1,4] # a new ferrule is auto-generated for each wire
  - # attach connectors (separetely from ferrules)
    - W1: [1-4]
    - X1: [1-4]
  -
    - F_10_1: 1 # manually defined ferrules are treated like regular connectors,
                # thus requiring a pin number
    - W1: 2
  -
    - F_10_1: 1
    - W1: 3
