Product Description
A compact and reliable 3.3V step-down power module,
measuring only 17×11×3.6mm. It efficiently converts a wide input voltage range of 4.75V to 23V into a stable 3.3V output capable of delivering up to 1.5A continuous current.
Designed for space-constrained projects demanding clean power, it is the perfect power solution for 3.3V microcontroller platforms like ESP32 and STM32.

Key Features
Stable & Precise Output: Provides a clean 3.3V (±2%) with low ripple, ensuring reliable operation for sensitive digital ICs.

Wide Input, High Current: Supports an input range of 4.75‑23V and delivers a continuous 1.5A output, sufficient to power small motors, servos, and multiple peripherals.

Robust & Durable: Built to operate reliably across an industrial temperature range (-40℃ to 85℃) with an optimized thermal design for sustained full-load operation.

Safe & Easy to Use: Features clear reverse-polarity markings. Includes pads for easy addition of external capacitors to protect against voltage spikes from inductive loads.

Excellent Value Bundle: Get 10 modules in one pack, ideal for prototyping, testing, and batch projects.

Typical Applications
IoT & Wireless Devices: Power for ESP32/ESP8266-based sensors, nodes, and communication modules.
