3.3V/5V Power Module for Development Board

Order a 3.3V/5V power supply module for your breadboard - get stable power for your circuits!

3.3V/5V Power Module for Development Board is a compact and reliable voltage source for your experiments. It provides stable power to microcontrollers, sensors and other components. You will be able to safely assemble and test prototypes of electronic devices. This module is compatible with standard solderless breadboards. It eliminates the need to use external power supplies or redesign the circuit.

This module solves the key problem of any electronic experiment - providing clean and stable energy. It converts input voltage (such as from USB or battery) into precise 3.3 or 5 volts. These are the two most common standards in the world of microcontrollers and digital electronics. Your circuits will operate correctly without the risk of component damage due to power surges.

• Two stabilized outputs 3.3V and 5V to power most components.

• Simple and reliable integration with standard breadboards.

• Overload and short circuit protection for the safety of your experiments.

• Compact dimensions and the ability to power from various sources.

• LED indication presence of voltage at each of the outputs.

How does this voltage stabilizer work?

The module is built on the basis of a linear or pulse voltage stabilizer. It accepts input voltage ranging from, for example, 6.5V to 12V. An internal circuit reduces and stabilizes this voltage. The output produces an accurate and constant value of 3.3V or 5V. The module automatically compensates for input voltage fluctuations and load changes.

The key advantage is built-in stabilization. Even if the input voltage from the battery drops, the output remains unchanged. This guarantees stable operation of microcontrollers and digital circuits. Protection circuits turn off the output in case of overload or short circuit. You can experiment without the fear of burning expensive components such as Arduino or sensors.

Technical characteristics and practical application

Specific parameters may vary, but typically the module has the following characteristics. Input voltage: 6.5V – 12V (often via 5.5x2.1mm DC connector or terminals). Output voltages: 3.3V and 5V with an accuracy of ±0.1V. Maximum output current: about 700-1000 mA for both channels in total. Equipped with LEDs to indicate switching on and presence of output voltages. The case is made in the form of a board with two rows of pins for installation in a breadboard.

The functionality of the module makes it a universal power center on a breadboard. You can power your Arduino board from it, leaving the USB port free for programming. Connect multiple sensors, LEDs or servos at the same time. Switch between voltages 3.3V and 5V depending on the logic of the microcircuits used. Organize neat power distribution through the breadboard buses.

This module is indispensable for training, prototyping and testing. When studying electronics and programming microcontrollers in schools and universities. When developing and debugging device prototypes before creating a printed circuit board. For creating temporary or test stands and measuring installations. It saves time and makes the work process much more convenient and safer.

Using the module is very simple. Insert its pin headers into the center of the breadboard. Provide input voltage from an adapter, power bank or 9V battery box. Use a jumper or switch to select the desired output voltage (3.3V/5V). Connect the breadboard power rails to the module output terminals using wires. LEDs will confirm that the module is ready for use.

The power supply module is compatible with all common development boards (400, 830 points and others). It fits harmoniously into the workspace without taking up much space. The low profile allows it to be installed even on assembled circuits. The quality of the components ensures long and reliable operation without overheating.
