Because many generic manufacturers produce this specific model, a single, official document can be hard to find. This article serves as a comprehensive breakdown of the HW-131, decoding its specifications, analyzing its circuit design, and providing the critical technical details usually found in a manufacturer’s datasheet. It supports input voltages of 6

Can serve as a 5V input or a 5V output to power other peripherals.

Do not exceed 12V input, as this can damage the regulators.

The Hw 131 is a dual-output, breadboard-friendly power supply module. It accepts a wide input voltage range (typically 6.5V to 12V DC) and provides two regulated outputs: and +3.3V .
