Hw-133-v1.0 Datasheet < 2027 >

: Many modules use the same MP1584 IC. The HW-133-v1.0 distinguishes itself with a well-designed PCB layout that prioritizes good thermal performance through the use of thermal vias, a feature that is often overlooked on cheaper clones. This attention to design ensures more reliable operation under sustained high loads.

: By using high-frequency switching, this module minimizes energy loss as heat compared to linear regulators.
