Mitchelectronics Simple Power Supply Project Kit

The Mitchelectronics Simple Power Supply Project Kit is a beginner-friendly electronics build that generates 3.3V, 5V, 9V and approximately -9V outputs from a single 9V PP3 battery. It is designed to help users build a compact, multi-output power source for prototyping and hobbyist projects.

Overview

Once assembled, the unit provides four DC outputs: a stable 3.3V, 5V, 9V, and an approximate -9V. This makes it a practical bench tool for powering microcontrollers such as Arduino, sensors, op-amp circuits and other low-voltage electronic projects that require different supply rails. The 9V PP3 battery is not included and is sold separately.

Key Features

• Multi-Voltage Outputs: Delivers 3.3V, 5V, 9V and approximately -9V from one 9V PP3 input.
• Surface-Mount Regulation: An AMS1117 surface-mount device (SMD) regulates the 3.3V output, offering practice with modern SMD components.
• Educational Build: Suited to beginners learning soldering, component identification and circuit assembly.
• Compact Printed Circuit Board: The PCB measures 43 mm by 59 mm, resulting in a neat and portable finished unit.
• Complete Kit: Supplied with all necessary components required for assembly.

Build Experience

The kit provides a hands-on introduction to soldering and circuit assembly. Working through the build reinforces practical electronics skills, including component identification and handling of an SMD regulator alongside through-hole parts. The finished unit weighs approximately 25 g.

Applications

The power supply suits prototyping benches and hobbyist projects that need several voltage rails from a single small battery. Typical uses include powering Arduino microcontrollers, sensors and op-amp circuits. The kit offers a hands-on introduction to soldering and circuit assembly, resulting in a practical multi-voltage power source for bench use.
