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 L298N Motor Driver Module.
While the internal chip is the STMicroelectronics L298N (a legacy dual H-bridge), the HW-133 refers to the module design—specifically the v1.0 PCB layout that integrates the chip with heat sinks, 5V regulation, and convenient screw terminals.
The datasheet for HW-133 is distinct from the official L298N chip datasheet. The chip datasheet talks about internal transistors and logic gates; the HW-133 datasheet tells you how to not burn your house down while plugging it into an Arduino.
