This module is engineered to accept a higher input voltage and efficiently convert it to a lower, stable output voltage. With its ability to handle up to 3A of current and support a broad input and output voltage range, the HW-133 v1.0 is a versatile building block for various power-sensitive electronics projects, automotive applications, and industrial systems.
: Always measure the output with a multimeter before connecting your load to ensure the potentiometer is set to the correct voltage.
Roughly 22mm x 17mm x 4mm, making it significantly smaller than standard LM2596 modules. Performance Review Pros: Hw-133-v1.0 Datasheet
