: While rated for 3A, the module can get hot. If drawing more than 2A continuously, it is recommended to add a small heatsink or provide active cooling.
The is a compact, high-frequency DC-DC Step-Down (Buck) Converter module based on the MP1584EN control chip. It is widely used in hobbyist electronics, drone technology, and DIY projects where space is limited but power efficiency is critical.
I’ve attached a photo of the board front/back.

is an excellent, low-cost power solution for portable electronics and DIY kits. Its balance of power density and high efficiency makes it a "go-to" for hobbyists who need more current than a linear regulator can provide without the footprint of a full-sized buck converter. between this module and the standard for a specific project? HW-133 Mini Step Down Buck Module | Daraz.com.bd
The is a popular adjustable buck (step-down) DC-DC converter module, often featuring the LM2596 voltage regulator. It is widely used in DIY electronics to convert higher DC voltages down to stable, lower levels (e.g., dropping 12V or 24V down to 5V or 3.3V). Technical Summary & Field Performance
However, due to inconsistent labeling by Chinese manufacturers, some sellers list the Hw-133-v1.0 as a similar to the HC-SR04. Therefore, before working with any board labeled Hw-133-v1.0, always visually confirm its components. : While rated for 3A, the module can get hot
Measure the voltage across OUT+ and OUT- using a digital multimeter.
Interfacing the Hw-133-v1.0 with a microcontroller is straightforward. Below is the most common connection for an .
Most HW-133 series adapters are classified as and no longer manufactured. Key considerations include: It is widely used in hobbyist electronics, drone
: Major electronics distributors like DigiKey maintain datasheet links and product documentation
(If your HW‑133 differs from this assumed class, tell me “different class” and I’ll adapt.)
Automatically turns off if the chip exceeds safe temperatures.
Converting a 12V or 24V lead-acid battery for USB charging (5V).
While a single, unified "HW-133-v1.0 datasheet" from a single manufacturer is rare, the necessary information is easily found. To get the most comprehensive technical data:
