If you are reading the HW-133 datasheet, you are likely holding a small, red PCB with a distinct blue potentiometer and a cluster of pins. This is the .
: The HW-133B is a newer variant of the module, often featuring a fixed 5V output and a different input range. For instance, the datasheet for the HW-133B specifies an input voltage of DC 7V-28V and a fixed 5V output, compared to the adjustable 0.8-20V output of the HW-133-v1.0. The HW-133-v1.0 offers more flexibility due to its adjustable output. Hw-133-v1.0 Datasheet
