DZS Elec XL6009 DC-DC Booster Regulator Module Input 3-32V to Output 5-35V Instead of LM2577 with Digital Tube Display Step-up Module

I had originally bought this to boost the 5V Rail of my LiPo battery for a weather balloon launch, taking the 5V rail with roughly 100mA, and raising its potential to 12V.It did this perfectly. I was able to finely tweak it to 12V, swapping the display to see input/output was also an amazing bonus as I could read my input rail used to power several devices.Launched the craft with the relay on board, and it withstood -50 C usage perfectly with nothing more than shrinkwrap plastic surrounding the chipset.Overall, worked exactly to what I needed. If I had a grip, the Digital Screen to display the Voltage is missing an additional unit space, which would've helped for a bit more accuracy.However, it gave me a 4.8V input, and boosted its low current of 100mA to 12V no problem at all, which was then used to power a Kipp-Zonen SMP10 Pyranometer for a weather balloon flight with excellency.If I ever need more micro boosters, these are a definite go-to for me. Work great with a Phone LiPo battery pack I used for the balloon flight.

Used them for a senior design project and were the exact thing we needed to get our project running.Two of them had the diodes fry up, but that was due to our negligence. Luckily they were cheap enough that it didn't completely break our budget. Would order these again in the future. There are durable enough that you can use them wherever and the LED display was convenient to have when fine tuning the potentiometer. Otherwise we would have had to have a multimeter attached, it just made things easier. Overall a great product!

I was going to return it because it wasn't correctly sensing vIN so the vOut was off by a wide margin.I decided to let it "burn-in" for several hours overnight and that did the trick, works great now.

This item was used to restore a 40V Ryobi battery back to life.

I use this is a manufacturing facility for checking the voltage output of custom made batteries we have in house. So far out of 100 pieces ordered we have had only 1 have a malfunctioning reader board. These little boards are tough, and easy to work with. I will be a repeat buyer for sure.
