The Breadboard Power Supply Module 3.3V-5V is a compact power supply board that plugs directly into the end of a standard MB102 breadboard — its output pins slot into the breadboard’s positive and negative power rail strips so the entire breadboard is powered immediately without needing any jumper wires between a separate power supply and the breadboard. This breadboard power supply accepts input from either a DC barrel jack (6.5V to 12V) or a USB cable, giving the flexibility to power the breadboard from a wall adapter, a power bank, or a laptop USB port depending on what is available at the workbench.
The 5v 3v breadboard power supply has two independent output channels — one for the left power rail strip and one for the right — each with its own jumper that selects either 3.3V or 5V independently, so a builder can run 5V on one side of the breadboard for an Arduino and 3.3V on the other side for a 3.3V sensor in the same circuit without any additional regulator. The 3.3 to 5v breadboard module delivers up to 700mA total, sufficient for Arduino Uno and Nano boards with a small number of connected sensors.
Available from StemVolt, offering quality electronics parts at competitive prices. This mb102 breadboard power supply is ideal for Arduino sensor prototyping and electronics learning builds in India.
