Having precise, stable voltages within +/- 0.05V means less troubleshooting of power related issues and ensures components are happy and healthy! but without shelling out for a variable bench power supply. Rock solid power in all the commonly used voltages. Removing chunky components like DC jacks, switches and voltage regulators from the breadboard frees up precious space for the actual project, along with fewer messy jumpers and wires. So I decided to design something that could do one job - power any breadboard - and do it really well, with enough options to make it indispensable for small prototyping projects. Nothing kills maker-mojo faster than battery anxiety! Also, it can be useful to save those 5V / 3.3V rails for powering something else, rather than just feeding a breadboard.īatteries. Useful for testing, but it adds to the jumper clutter.
A must-have to be sure, but expensive, big and (arguably) overkill for low power circuit design and general hobbyists. For prototyping, nothing beats a breadboard! But how to provide power to the little black and red rails that fuel our designs? There are a couple of conventional options:Ī bench/lab variable power supply.
