Loading 3D model… large boards can take a moment.
The Boardoza SPX1117-3V3 Breakout Board is a compact linear voltage regulator board designed to provide a clean, stable, and low-noise 3.3V output for a wide range of embedded and electronic applications. Built around the SPX1117M3-L-3-3/TR low-dropout (LDO) voltage regulator, it efficiently converts higher DC input voltages into a regulated 3.3V supply suitable for sensitive digital and analog circuits.
Thanks to its low dropout voltage, high output current capability, and integrated protection features, this breakout board is an excellent choice for powering microcontrollers, sensors, communication modules, RF circuits, and development boards where stable 3.3V power is essential.
