The Breadboard Power Jumper connects the edge rails (bus strips) of a standard solderless breadboard together while also providing clip points for power leads. This design was heavily influenced by a design from IMSAI Guy with with slight modifications to the PCB shape and with the addition of manufactured test points.
Read More Breadboard Power JumperWhile designing a sensor breakout PCB I decided it would be useful to include power input protection in the form of reverse voltage and overvoltage protection. This circuit is a combination along with slight modification of two circuits I found online. In this article I build up a prototype for functional testing and also perform some circuit characterization. This is a prototype circuit that I plan to implemented in future projects.
