Chips like the ESP32, ESP8266 Wi-Fi transceivers, and various modern sensors will be instantly destroyed if powered by 5 Volts. This AMS1117-3.3 breakout module provides the perfect plug-and-play solution. It features a factory-calibrated AMS1117 Low Dropout (LDO) linear regulator, surface-mounted alongside all the necessary input and output smoothing capacitors, ensuring a highly stable, noise-free 3.3-Volt output right out of the box.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\" id=\"p-rc_da87b27accadd0cc-328\"\u003e\u003cspan class=\"citation-423 citation-end-423\"\u003eDesigned for rapid prototyping and easy integration, the module takes a slightly higher unregulated input voltage ideally from a 5-Volt USB line or a 9-Volt battery and efficiently steps it down to a continuous 3.3
