Breadboard Power Supply (3.3V / 5V)
Deliver clean, regulated power directly to your breadboard with this compact dual-voltage power supply module. Plug it onto any standard breadboard, connect a DC adapter or USB cable, and instantly get selectable 3.3V or 5V on both power rails - no more messy jumper wires from external regulators.
Specifications
| Output Voltages | 3.3V and 5V (independently selectable per rail via jumpers) |

| Voltage Regulator | AMS1117-3.3 & AMS1117-5.0 (LDO, low dropout) |
| Max Output Current | 700 mA per rail (combined <= 1A recommended) |
| Output Connector | Dual-row header pins (fits standard 830/400-point breadboards) |
| On/Off Switch | Built-in slide switch for power control |
| LED Indicator | Power-on LED for each rail |
| Board Dimensions | ~53 x 35 mm |
| Type | Power Supply Module / Breadboard Accessory |
| Origin | Original / Authentic |
| Warranty | 7-day warranty on manufacturing defects |
| Support | Email & WhatsApp 24/7 |
Key Features
- Dual-Voltage Output: Set each breadboard rail independently to 3.3V or 5V using onboard jumpers - ideal when your project mixes 3.3V sensors with a 5V microcontroller.
- Plug-and-Play Design: Header pins slide directly into breadboard power rails; no soldering, no adapters, no wasted breadboard space.
- Flexible Input Options: Power via a standard DC barrel jack (wall adapter) or USB cable - work at your desk or on the go.
- Built-In Power Switch: Slide switch lets you cut power without unplugging anything, protecting your circuit during wiring changes.
- LED Power Indicators: Instantly confirm each rail is active - simple visual debugging at a glance.
- Stable Regulated Output: AMS1117 LDO regulators provide clean, low-noise voltage for sensitive microcontrollers, sensors, and ICs.
- Compact & Lightweight: Sits neatly at the end of the breadboard without blocking rows.
Why Choose This?
- 100% authentic module from trusted component suppliers
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse
- Expert technical support included - get help wiring your first circuit
- Essential accessory every breadboard prototyper needs on the bench
Project Ideas
- Arduino & ESP32 Prototyping: Power your microcontroller and peripheral sensors at different voltages on the same breadboard without juggling multiple USB cables.
- Mixed-Voltage Sensor Circuits: Run a 3.3V BME280 or MPU6050 alongside a 5V relay module - each on its own rail.
- LED & Motor Driver Testing: Quickly bench-test LED strips, small DC motors, or servo circuits with a stable 5V supply.
- Logic-Level Interfacing Labs: Teach or learn voltage-level concepts by having both 3.3V and 5V available side by side.
- Portable Field Projects: Pair with a 9V battery (via barrel jack adapter) for on-the-go breadboard power at hackathons or field demos.
What's in the Box
- 1 x Breadboard Power Supply Module (3.3V / 5V)
- Voltage-selection jumpers (pre-installed)
- Documentation and support materials
Getting Started
- Align the Pins: Press the module's header pins into the + and power rails at the end of your breadboard.
- Set Voltage: Place each jumper on the 3.3V or 5V position for the corresponding rail.
- Connect Power: Plug in a 9V-12V DC adapter to the barrel jack or a USB cable.
- Switch On: Slide the power switch - the LED(s) will light up confirming active output.
- Build Your Circuit: Your breadboard rails now carry clean, regulated voltage. Start prototyping!
Frequently Asked Questions
Can I run 3.3V on one rail and 5V on the other simultaneously?
Yes - each rail has its own jumper, so you can independently select 3.3V or 5V per side. This is one of the module's biggest advantages for mixed-voltage projects.
