Hw-133-v1.0 Datasheet _verified_ -

In communication equipment, HW-133 adapters facilitate:

Where the "HW-133" naming convention appears across various electronics, the "v1.0" suffix specifically refers to a well-established, widely available variant based on the switching regulator IC. It is not to be confused with the Xilinx family of programming adapters (e.g., HW-133-PC44), which are entirely different devices. This guide focuses solely on the power converter module.

The functional reliability of the HW-133-V1.0 rests on its high-frequency Buck topology. The on-board MP1584EN IC integrates a low- Hw-133-v1.0 Datasheet

Connect your input power supply (e.g., a 12V battery or 24V adapter) to the and IN- pads.

It may take several full counter-clockwise turns before you see the voltage start to drop. Final Connection:

: While rated for 3A, the module can get hot. If drawing more than 2A continuously, it is recommended to add a small heatsink or provide active cooling.
