Integrating into tight spaces where standard LM2596 modules are too large.
At first glance, it looks like just another generic breakout board. But if you try to search for an official "HW-133-v1.0 Datasheet," you might hit a wall. Why? Because the "HW" prefix usually points to a hardware reference design rather than a proprietary chip. Hw-133-v1.0 Datasheet
Reviewing the HW-133-v1.0 datasheet is an exercise in patience. It typically arrives as a low-resolution PDF, often slightly blurred around the edges. Integrating into tight spaces where standard LM2596 modules

The datasheet for this specific hardware revision (v1.0) typically aligns with the following parameters: Input Voltage Range 4.5V to 28V operating range. Output Voltage : Adjustable from 0.8V to 20V via an onboard trimpot. Current Output : Rated for a 3A maximum (peak), though continuous operation is best kept around 1.5A to 2A without external cooling. Efficiency : High efficiency up to , largely due to its pulse-skipping mode for light loads. Switching Frequency : Fixed at a high
