What is the Simple Power Module SMD Trainer?

The Simple Power Module SMD Trainer kit is a module that provides two regulated output voltages from a single input voltage. These two voltages are 5V and 3.3V, and can be used to power most maker circuits including microcontrollers, sensors, shields, and add-ons. Furthermore, each regulated output has its own fuse, which protects the regulators and the circuit being powered.

As the aim of this kit is to introduce you to SMD soldering, the theory behind the circuit will not be covered here.

Use this kit to test out your soldering skills!

What can you do with the Simple Power Module SMD Trainer?

Besides the obvious use of SMD training, the Simple Power Module can be used in many different projects. For example, the Simple Power Module SMD can be used for converting a 9V battery into a 3.3V source suitable for a Raspberry Pi Pico microcontroller. The module could also be used for providing 5V to a micro servo and a 3.3V source for a sensor.

The spacing between the input and output have been designed to fit across a breadboard, meaning that this module is breadboard friendly. As such, you can use this module with breadboard designs, thereby allowing for reuse and modification.

Construction Tips

3D Printable Jig

To help keep the board stable when soldering, you can download a free STL model of a basic jig that can be 3D printed with all common 3D printers. Watch out for the mounting hole pins as they may be vulnerable to snapping if using a low infill density, low wall thickness, or thick layer heights. Additionally, do not use hot air to solder the PCB when using the jig as you will melt the jig.
