For anyone who may not have noticed, all of the [Fritzing] parts that I use to illustrate my circuit diagrams, and a few more, are available on the
Fritzing parts list on this website. While some of these duplicate the efforts of others, my interest in Fritzing is primarily for the breadboard illustrations that it generates. As such, nicely rendered images of parts are more important to me than minimising the size of the image file and where I have duplicated a previous effort it has been to provide a more ‘attractive’ breadboard image of that part—the pcb and schematic components are essentially identical.
I have recently added a number of components associated with RS485 communications and sensors—a couple of RS485-to-TTL interface modules:


an RS485-to-USB adaptor

and ‘icons’ for a generic RS485 sensor

These components are used to illustrate the discussion surrounding the use of RS485 sensors elsewhere on this website.
