Category: Power

This power supply module is based on the AMS1117 3.3V regulator. It is capable of regulating a wide range of input voltage (4.0 to 12V) down to a fixed 3.3V output at up to 1A (Vin = 4.5V). Standard 0.1" header pins provide a means of connecting to its input and output terminals. These header pins have also been conveniently placed so that the module can be inserted face down into standard...

Abigail Q. ★★★★★

Had a project that needed a stable 3.3V rail from a 9V battery, and this little board handled it perfectly without any heat buildup. The screw terminals made wiring a breeze.

Claire F. ★★★★★

Fed my Arduino Nano through the 12V input without any voltage sag, and the fixed 3.3V output is exactly what I needed. The compact board fits neatly on perfboard too.

Daniel ★★★★★

I’ve been using this to power a small ESP8266 board and it gives a steady 3.3V even when my input voltage dips to around 4.5V. The board’s compact size makes it easy to fit into tight enclosures.
