I have come to like the Scheme-It tool from Digikey, it works pretty well for the task you describe. I have also used Lucid-chart and draw.io. The Latter interfaces with the google office tools pretty well.


A free and pretty nice vector drawing tool is GravitDesigner. It can handle all sorts of graphics. You can try it on-line or download it for almost any device including Windows, MacOS, Android, ChromeOS, and Linux.
