Power modules — buck/boost converters, voltage regulators and battery charging boards.
Power modules supply the right voltage to electronics projects, which is essential for stable, safe operation. Buck converters step voltage down, for example from 12 V to 5 V, while boost converters step voltage up, which is useful for running 5 V devices from a single lithium cell. Voltage regulators provide stable output, and battery charging modules such as TP4056 charge lithium batteries safely. Breadboard power supplies provide 3.3 V and 5 V for prototyping. Check the input and output voltage range, maximum current and efficiency before ordering. Adjustable modules let you set the output voltage precisely.
