Compact and effective
Small footprint makes it easy to fit into tight enclosures. The potentiometer is a bit sensitive, so take your time adjusting the voltage. Overall a great little board.

Good quality, runs slightly warm
The build quality is solid and the soldering points are clean. It does get a bit warm when pushing close to 2A, so I added a small heatsink. Otherwise, excellent performance.

Essential for learning electronics
Bought this for my university embedded systems course. It's very easy to use on a breadboard and the output is very consistent. Highly recommended for students.

Perfect for Arduino projects
This module works flawlessly with my Arduino setups. The voltage adjustment is smooth and stable under load. Great value for the price.

Reliable power conversion
We use these in our makerspace for various prototyping needs. They have held up well over months of continuous use by different members. No failures so far.

Exceeded expectations
I was skeptical about the low price, but this regulator performs just as well as branded versions I've used before. Stable output even with noisy input sources.
Q: Does this come with headers pre-soldered?
A: No, the module is shipped without headers to allow flexibility in mounting. You will need to solder your own pins or wires based on your project needs.
Q: Can this module step up voltage or only step down?
A: This is a buck converter module, meaning it can only step down voltage. The input voltage must be higher than the desired output voltage.
Q: Is there an LED indicator on the board?
A: Yes, there is a blue power LED that lights up when the module receives input power, helping you verify connections quickly.
Q: Can I connect this directly to a 12V battery?
A: Yes, as long as the battery voltage stays within the 4.0V to 35V input range, it is safe to connect directly. Ensure polarity is correct.
Q: What is the minimum difference required between input and output voltage?
A: For optimal performance, we recommend keeping the input voltage at least 1.5V to 2V higher than the target output voltage.
