Review on ⚡️ DZS Elec XL6009 DC-DC Booster Regulator Module with Digital Tube Display - Step-up Voltage Converter 3-32V Input to 5-35V Output, Replacing LM2577 by Joseph Winfrey

I was very happy with this device until I realized it was causing the problem I've been struggling with for the last 3 weeks. I installed it about 5 inches from my GPS receiver and it generates so much RF noise that the GPS receiver cannot lock. Turning off this unit allows the GPS receiver to operate. This causes crashes when the GPS receiver is within 3 feet. Therefore unsuitable for my application. I found this by accident on other tests and placed this unit a few feet from an already working GPS receiver and it lost lock almost immediately. So now I have to throw away those 4 devices I bought and find another one. product for this application.
