Most HW-133 series adapters are classified as and no longer manufactured. Key considerations include:
: Consumes roughly 75% less idle current than LM2596 modules.
: 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.
⚠️ : If your Hw-133-v1.0 has two large metal canisters (transducers), it is an ultrasonic sensor. In that case, the specs will be: 5V, 15mA, 2cm-400cm range, with Trig and Echo pins. Hw-133-v1.0 Datasheet
For more information on the HW-133-V1.0 datasheet, please refer to the following resources:
The is an ultra-compact, high-efficiency DC-DC step-down (buck) voltage regulator board designed for space-constrained electronics projects. Built around the high-frequency Monolithic Power Systems MP1584EN switching regulator integrated circuit, it efficiently drops higher input voltages down to a lower, stable output voltage. This comprehensive datasheet guide breaks down its core technical specifications, pinout configurations, applications, and operating best practices. Technical Specifications & Performance
Note: The output voltage must always be at least 1.5V to 2V lower than the input voltage for proper buck regulation. Thermal Management Most HW-133 series adapters are classified as and
The is an ultra-small, high-efficiency DC-DC step-down (buck) voltage regulator module. It is widely integrated into robotics, microcontrollers, and aerospace modeling due to its compact form factor and 3A peak output current capability . The module typically relies on the highly popular MP1584EN high-frequency switching regulator chip (or equivalent variants like the XM1584 or GW1584) paired with an onboard multi-turn potentiometer for adjustable output tuning.
Thanks to its diminutive footprint and high efficiency, the HW-133-V1.0 module is commonly deployed in:
: Allows for a high-voltage, high-current output in a tiny form factor. Low Quiescent Current Even when input voltages briefly spiked past 20V
If the output is "jittery," adding a 100uF electrolytic capacitor across the OUT+ and OUT- pads can help smooth out the ripple.
Exposed multi-layer copper vias located directly under the MP1584EN IC to sink heat away from the silicon die into the back of the PCB. Key Architectural Advantages High Efficiency vs. Linear Regulators
