Generate Fritzing components that match your stripboard

Fritzing Stripboard Generator

Generates Fritzing components matching your particular stripboard.

Inspired by Robert P Heller's project having a similar aim: https://github.com/RobertPHeller/fritzing-Stripboards

Installation

pip install fritzing-stripboard

You can also install the in-development version with:

pip install https://github.com/coddingtonbear/fritzing-stripboard/archive/master.zip

Use

fritzing-stripboard /path/to/board.yaml /path/to/output/part.fzpz

Defining Your Board

While digging through my project supplies, I happened across a large collection of stripboards that look like this:

Although there are stripboards available online for Fritzing, none quite looked like this. Luckily, though, generating a Fritzing part for this board can be done easily with just a little bit of yaml:

meta:
  title: 3-5-5-2 Board with Solid Bus
  label: 3-5-5-2
width: 50.5
height: 100.5
board:
  - grid:
      components:
        - shared_bus:
          - bus: A1:T1
          - bus: E1:E36
          - bus: Q1:Q36
        - shared_bus:
          - bus: A37:T37
          - bus: T2:T37
          - bus: A2:A37
          - bus: K2:K37
        - drilled_rows: B2:D36
        - drilled_rows: F2:J36
        - drilled_rows: L2:P36
        - drilled_rows: R2:S36

The above will generate a board that looks like:

The Grid

Definitions for boards use excel-like grid square ranges for defining where new bus (trace) or drilled hole elements should appear:

Grid supports a handful of properties including:

• components: A list of "Components" described below in "Components".
• meta: An optional object containing any of the following keys:
  • origin: The position at which the grid is positioned, relative to the upper-left corner, in millimeters. By default: [0, 0].
  • pitch: The pitch of grid elements in millimeters. By default: 2.54.
  • back: Whether there is copper only on one side of the board. In such a case, you need to install your ICs on the side without printed traces. You can describe your stripboard's grid as you see it, but it will be mirrored when generated. Note: When using this, you will also want to set origin to be the upper-right corner of your grid instead of leaving it unset. By default: False.

Components

bus or drilled

These create a line or a line of drilled holes. For example, bus is used for creating this:

Each bus or drilled range will be assigned its own "bus" (a.k.a. "net") unless wrapped by shared_bus as you've seen in the example above.

drilled_rows or drilled_columns

These create an array of rows or columns. For example, drilled_rows is used for creating this:

Each row or column of the range will be assigned its own "bus" (a.k.a. "net") unless wrapped by shared_bus.

shared_bus

bus and drilled ranges by default each get their own bus. If your stripboard has a more complex layout (like in the example), you can use this 'component' for causing all components below it to share the same bus.
