AMS1117-3.3V DC-DC Step-Down Voltage Regulator Power Module for Arduino & ESP32 in Pakistan

Overview

The AMS1117-3.3 Power Module is a compact, linear voltage regulator designed to step down higher DC voltages to a fixed 3.3V output. Built around the popular AMS1117 low-dropout (LDO) linear regulator IC, this module features onboard filtering capacitors to ensure clean, noise-free power delivery.

It is an essential power utility for engineering student projects, sensor interfaces, and wireless IoT nodes that require a stable 3.3V rail but are being supplied by a standard 5V system or battery pack.

Key Features

• Stable 3.3V Output: Filters and regulates fluctuating inputs to provide a clean 3.3V line.

• Onboard Power Indicator: Includes a small red SMD LED that immediately lets you know if the board is receiving power.

• Dual-Pin Layout: Designed with a 2-pin header format for both input and output, making it extremely easy to hook up with jumper wires.

• Breadboard Friendly: Standard 2.54mm pitch pins mean it can plug right into a breadboard layout for rapid prototyping.

• Compact & Lightweight: Small footprint allows it to be tucked into tight custom enclosures or soldered directly onto a matrix PCB.
