⚡️ MB102 Breadboard Power Supply Module: Dual Voltage Prototyping
Simplify and stabilize the power delivery to your breadboard projects with the MB102 Breadboard Power Supply Module. This essential tool snaps directly onto standard MB102 solderless breadboards , making it incredibly fast and easy to power your circuits without the clutter of external regulators and wiring.
It's the ultimate time-saver, designed to support modern microcontrollers and logic circuits by providing independent, switchable dual voltages.
✨ Key Features & Prototyping Benefits
FeatureTechnical SpecificationPractical AdvantageDual Rail ControlIndependent control for each breadboard power rail.Simultaneously run a 3.3V microcontroller (like an ESP) and 5V peripherals (like relays) on the same board.Switchable OutputOutput can be switched between 0V, 3.3V, or 5V on each rail.Maximum flexibility to quickly test different voltage requirements or completely disconnect power from one side.Convenient Input2.1mm Barrel Jack (DC 6.5V - 12V)Easily powered by a standard 9V battery snap connector or a wall adapter.Integrated USB PortOn-board USB-A PortDirectly power development boards (like some Arduinos) and automatically tie the breadboard ground to the dev board ground, simplifying connections.Safety & ControlON/OFF Switch with indicator LEDConveniently power cycle your circuit without having to plug and unplug the power source.External LeadsTwo sets of 3.3V/5V DC output plug pinsEasily run power off the module to external components or other sections of your circuit.
