AMS1117 3.3V Voltage Regulator Module – Power Supply for Arduino, ESP8266, and 3.3V Devices
The AMS1117 3.3V Voltage Regulator Module is a compact and reliable power regulator designed to convert higher voltages (like 5V) down to 3.3V for use with low-voltage devices. It’s an essential component for powering ESP8266, ESP32, NRF24L01, and other 3.3V logic circuits in embedded and IoT projects.
 
Key Features:
Fixed 3.3V Output
Regulates input voltage to a stable 3.3V output for sensitive components.
Wide Input Range
Accepts input voltage from 4.5V to 12V (recommended 5V–7V for optimal performance).
High Compatibility
Ideal for ESP8266, ESP32, NRF modules, and 3.3V sensors.
Onboard Capacitors
Built-in input and output filter capacitors for voltage stability and noise reduction.
Plug-and-Play Interface
Simple 3-pin interface: VIN, GND, and VOUT for easy breadboard or PCB integration.
