The green board above represents a Raspberry Pi model B board. These lines are created by selecting a pin of a device and dragging to another pin on another device. Fritzing recognizes an LED is a device that has polarity- when you mouse over the LED pins, a tooltip will tell you which is the anode and which is the cathode. Wires are shown as blue lines. All the components in the breadboard view actually resemble the real-world components.įor example, in the circuit above, the resistors look like real resistors right down to the color coded bands. The LED resembles a physical LED, right down to pin names. You can take this diagram and easily recreate the circuit if you have the components. The breadboard view represents the physical implementation of the circuit. Here’s an example of a simple circuit to read a button push and blink an LED with a Raspberry Pi: Fritzing understands the parts of a component, specifically how pins can be connected between components.
The other two views are an electronic schematic view and a printed circuit board (PCB) view. The breadboard is one of three available views. It has a library of common electronic components that you can drag and drop on top of a virtual breadboard. Mark Hatch, The Maker Movement Manifestoįritzing is a drawing tool. Still, they should be roughly in the same place in the breadboard view as they are on the real part.Sharing what you have made and what you know about making with others is the method by which a maker’s feeling of wholeness is achieved. These components don’t connect to anything other than the board itself, so the errors in their position won’t affect the position of other Fritzing parts.
When measuring those, you don’t have to be as precise as with the connectors. Since the breadboard view should look the same as the real component, it’s also a good idea to measure position of components soldered onto the breadboard, like capacitors, resistors and ICs. Measuring those is usually not a good idea, since any measurement you take will always be less accurate than the dimensions you can find in datasheet. Dimensions of components like ICs can be found in their datasheet. For example, the pitch of the pin header is 2.54 mm (0.1 inch). Tip: Lots of components on the breakout board have standardized dimensions. The sensor is placed on a small breakout board, and since dimensions for the breakout board is not provided we’ll have to measure most things.įigure 3.
The steps will be almost the same for all of them, so let’s just focus on ML8511A for now. If the search comes up empty, then it’s time to get the caliper and start measuring.Īs an example for this guide, I will be making Fritzing parts for some of the sensors from the ROHM Sensor Evaluation Kit : UV sensor ( ML8511 ), hall-effect sensor ( BD7411G ) and color sensor ( BH1745NUC ). Even though nobody had made the Fritzing part yet, someone might have measured the dimensions for you. That’s when you’re going to have to improvise a little. You will probably be able to find a datasheet for the module on the breakout board, but not for the board itself. Sometimes, the part you’re designing will simply not have a datasheet typically if it’s a breakout board. Unfortunately, it won’t be always this easy. Manufacturers tend to put them on the last few pages.įigure 1. The dimensions are usually included in the datasheet, so that’s a good place to start. Finally, we will add some metadata and integrate all of it into a single Fritzing part! Step 1: Gather all the informationīefore we start drawing the vector graphics and designing the part, we will need all the information we can get, mainly the physical dimensions of the part to create the breadboard view, which should have the same dimensions as the real component. We will then use the graphics to create the source files for all three Fritzing views – the breadboard view, the schematic view and the PCB view.

In this guide, you will learn the basics of working with vector graphics using free Inkscape editor. Fritzing version 0.9.3b – available from.This tutorial will guide you step-by-step through the process of turning those components into Fritzing parts. Fritzing has quite a few electronic parts built-in and there are third-party libraries, but sometimes, your circuit might be using some new or rare component that isn’t included in any of them. The main advantage Fritzing has over other free circuit design tools like Eagle or KiCAD EDA is the ability to create the circuits in “breadboard” view – basically just like using real wires to connect real components on a real workbench. Fritzing is an open-source prototyping platform that allows its users to easily create electrical circuits.
