Breadboard Power Module

This is something that I wanted to do for a long time, but just never had the time. I own a few commercial versions of these, and was unfortunately never able to get one that actually fits my breadboard power rails... ( don't know why, as it is a standard breadboard. Another issue with the commercial unit(s) was that they overheated when powered from 12v, and the voltage output was also not very smooth and stable either. I decided to finally sit down and design my own, with a LOT of smoothing capacitors, as well as rail power indicators and status LEDs. A DC barrel connector is used to power the module, and it does NOT have an on-off switch, as the bench power supply has one already. no need for that, in my view anyway. I attempted to make something that takes up as little space as possible on the breadboard, and give access to as much development area as possible. I think I have succeeded in that part, with the downside that the module has quite a bit of "stick-out" on the side of the breadboard. This may be an issue for some, but, I don't find it cumbersome. When designing something that must fit into/onto another commercial project, the measuring always drives me quite crazy, as digital callipers are not always as accurate as we think they are. needless to say, this caused a few worried moments from the time of submitting this order to PCBWay for manufacturing until finally having it delivered and assembled... All the worries was not needed, as the measurements were spot on, and the manufacturing was perfect. The module fits the breadboard perfectly. Thank you PCBWay!
