What is this project about?
The Universal Power Supply Board is a versatile solution designed for powering low-power devices such as microcontroller units (MCUs), sensors, and modules. With superior load and line regulation features, it ensures stable and precise voltage outputs, making it an ideal choice for various applications.

How does it work?
The board is capable of accepting a wide range of input voltages, either AC or DC, from 8V to 28V. It efficiently converts the input to provide multiple output voltages, including:

• Fixed outputs: 3.3V, 5V, 12V
• Variable DC output: Adjustable for specific requirements
• Passthrough output: Matches the input voltage

With a load regulation of 60mV and a line regulation of 0.2%/V, the board guarantees minimal fluctuations and high reliability.

Step-by-step tutorial:

1. Assemble the board: Solder the components onto the PCB as per the schematic diagram.
2. Connect the input: Attach an AC or DC source within the 8V to 28V range.
3. Set the output: Use the onboard controls to configure the desired output voltage.
4. Test the setup: Use a multimeter to confirm stable output voltages.
5. Power the devices: Connect low-power devices like MCUs, sensors, or modules to the output terminals.
