The AMS1117 3.3V Voltage Regulator Module is a convenient, plug-and-play power supply board designed to step down higher DC input voltages to a precise 3.3V DC output.
The AMS1117 3.3V Voltage Regulator Module is a convenient, plug-and-play power supply board designed to step down higher DC input voltages to a precise 3.3V DC output. Based on the high-efficiency AMS1117-3.3 linear voltage regulator IC, this module is an essential power solution for driving 3.3V logic microcontrollers, wireless modules, and low-voltage sensors from 5V USB ports or 9V–12V power adapters.
The module features a built-in power indicator LED to confirm active operation and double-panel design with dual pin headers (2-pin input and 2-pin output) for easy breadboard, stripboard, and custom PCB wiring. Integrated thermal shutdown and current limiting protection ensure reliable performance and guard connected components against over-current conditions.
It is widely used in IoT projects, robotics, sensor conditioning, and microcontroller development environments. It is fully compatible with ESP8266 (ESP-01, NodeMCU), ESP32, Raspberry Pi, ARM Cortex, STM32, and 3.3V sensor interfaces.
