Multi-output Power Supply Module DC-DC 12V TO 3.3

The Multi-Output Power Supply Module provides three regulated DC voltage rails — 3.3V, 5V, and 12V — simultaneously from a single input between 6V and 24V connected through a standard 2.1mm barrel jack, making it a compact power distribution board for projects that need multiple different voltages at the same time from a single power source. This power supply module eliminates the need for three separate regulators or three separate power supplies in a multi-voltage project — connect one 12V or 24V DC adapter and all three output rails are live and regulated immediately, each with its own dedicated connection points on the board.

The 12v power supply module uses AMS1117 linear voltage regulators for the 3.3V and 5V output rails, delivering up to 800mA to 1A per rail depending on the input voltage and the heat dissipation of the board. Three power indicator LEDs — one for each output rail in different colors (red, blue, and green) — confirm at a glance that all three voltage rails are active and the module is receiving input power, without needing a multimeter to verify each rail separately.

The dc multi output power supply module provides both screw terminal connectors and 2.54mm header pins for each rail, giving the choice of soldering wires directly or using Dupont jumper wires for quick prototyping connections. The dc dc power supply module 6V to 24V wide input range accepts a variety of standard DC adapters, lab supplies, and batteries commonly. StemVolt offers fast and reliable delivery with trusted service support.
