Hw-133-v1.0 Datasheet Updated ❲DELUXE❳

: Field tests using a Raspberry Pi Compute Module 4 and solar arrays revealed that the HW-133-v1.0 includes effective internal transient suppression . Even when input voltages briefly spiked past 20V (due to solar transients), the module maintained a stable output without triggering destructive failure or internal crowbar circuits.

The is an ultra-small, highly efficient DC-DC step-down (buck) voltage regulator module widely used in robotics, embedded systems, and hobbyist electronics. Built on the high-frequency Monolithic Power Systems (MPS) MP1584EN buck converter IC , this miniature module converts a higher direct-current input voltage into a stable, lower output voltage. It serves as a modern, high-efficiency replacement for bulky, older linear regulators and larger buck converter boards. Core Specifications Overview Hw-133-v1.0 Datasheet

The module is a "go-to" for makers because it handles variable input sources (like 7.4V or 12V batteries) and converts them into a stable 5V or 3.3V supply for microcontrollers. It is frequently found in: Aviation Models : Used where weight is a critical factor. Environmental Monitoring Nodes : Field tests using a Raspberry Pi Compute

Under continuous load applications without external cooling, keep the current demand below 1.5A . Drawing close to 3A causes rapid thermal dissipation across the tiny Built on the high-frequency Monolithic Power Systems (MPS)

💡 Before connecting your sensitive electronics (like an Arduino or ESP32), connect the HW-133 to your power source and use a multimeter to measure the OUT+ pad. Turn the on-board trimmer potentiometer (the small brass screw) counter-clockwise to decrease the voltage until you reach your target. Key Features & Component Overview HW-133 v1.0 relies on the Monolithic Power Systems MP1584 architecture:

The HW-133 v1.0 is favored for its wide input range and high switching frequency, which allows for smaller inductors and cleaner power delivery. Specification 4.5V to 28V DC Output Voltage Range 0.8V to 20V DC (Adjustable via Potentiometer) Maximum Output Current 3A (Continuous: ~1.5A to 2A without heat sink) Conversion Efficiency Switching Frequency 100kHz to 1.5MHz (Typical: 1MHz) Output Ripple Operating Temperature -40°C to +85°C Dimensions 22mm x 17mm x 4mm Pinout and Connection Guide

The is a highly efficient, ultra-compact DC-DC buck (step-down) converter module, commonly identified by its use of the MP1584EN integrated circuit. Engineered for applications requiring a smaller footprint than the ubiquitous LM2596, this module offers superior efficiency and higher switching frequencies, making it ideal for powering sensitive electronics from higher voltage sources.
