## Description

Build your own breadboard-friendly adjustable power supply with this soldering kit. Based on the MIC2941 low-dropout regulator, it provides a guaranteed 1.25A output with only 40–400 mV dropout — far better than the LM317's typical 1.25–2.0V. This means you can generate 3.3V from as low as 3.7V input (three AAs or a lithium-ion battery). The kit includes all components and a PCB, ready to assemble in about 30–45 minutes with basic soldering skills. An output selection switch lets you quickly choose between 3.3V, 5V, or a continuously adjustable voltage via the onboard potentiometer. Key Features MIC2941 Low-Dropout Regulator – 1.25A guaranteed output with only 40–400 mV dropout 3 Output Modes – Switch between 3.3V, 5V, or adjustable (1.25V to input voltage minus 0.5V, 20V max) Onboard Potentiometer – Fine-tune the adjustable output voltage Short Circuit & Overheating Protection – Built-in safety features Input Protection Diode – Guards against negative voltages or AC power supplies Dual Input Options – 2.1 mm DC jack and screw terminal connector Dual Indicator LEDs – Visual feedback for high and low voltages On/Off Switch – Power control for the entire board Heat Sink Included – Keeps the regulator cool under load Ideal For Powering breadboard circuits at 3.3V or 5V Projects requiring adjustable voltage from battery or DC supply Beginner-friendly soldering practice Workbench power supply for prototyping Package Contents 1× PCB and all components (unassembled soldering kit) 1× Heat sink Note: Breadboard, battery clip, and DC power supply are not included. Requires a soldering iron, solder, and diagonal cutters for assembly. Resources Assembly Guide & Project Page (Adafruit Learn)
