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.
