Hw-133-v1.0 Datasheet [portable] Jun 2026

The module includes copper thermal vias beneath the MP1584EN IC and the main inductor to help spread heat through the PCB layers. While rated for up to 3A peak, drawing more than 2A continuously generates noticeable heat. For steady, high-current loads, affixing a small aluminum heatsink or providing active airflow is highly recommended. Implementation & Application Notes Reverse Polarity Risk

22 mm x 17 mm x 4 mm (or 25 mm x 20 mm x 4 mm depending on board trim) Module Pinout Configuration

Unlike complex ICs, this board is simple. Looking at the 4-pin header, you will find:

: Typically includes 50V rated electrolytic capacitors at input and output for ripple reduction. Hw-133-v1.0 Datasheet

: By optimizing device performance and power efficiency, Hw-133-v1.0 can contribute to more sustainable and environmentally friendly technologies.

It features a very low quiescent current (around 0.8mA), making it ideal for long-term battery monitoring.

The exposed copper will oxidize over time. The datasheet never mentions this, but conformal coating or simply accepting the board as a consumable part of your garden project is the way to go. The module includes copper thermal vias beneath the

The module operates within standard safe margins without auxiliary cooling components.

Use a precision screwdriver to turn the copper screw on the trimpot until the multimeter displays your desired operating voltage (e.g., 5.0V or 3.3V). Thermal Management Considerations

) is placed immediately next to the IC input pin. This layout effectively suppresses incoming voltage spikes and attenuates high-frequency EMI generated by the switching cycle. 2. Switching and Control Loop Implementation & Application Notes Reverse Polarity Risk 22

(If your HW‑133 differs from this assumed class, tell me “different class” and I’ll adapt.)

In the world of embedded systems and DIY electronics, breakout boards and sensor modules often carry cryptic silk-screen labels. One such common designation is . While not a mainstream IC from giants like Texas Instruments or Microchip, the Hw-133-v1.0 is widely recognized among hobbyists as a specific revision of a popular sensor module – typically a Raindrop / Water Level Sensor Module or a variant of the HC-SR04 Ultrasonic Distance Sensor.
