Review on 🔌 XL6009 XL6009E1 Boost Converter Module - DC-DC 3.0-30V to 5-35V Output Voltage Adjustable Step-up Converter Board Module (5pcs) - Enhanced SEO by Matthew Frandsen

When I first tested one of the modules, I noticed that there is a 50V capacitor soldered on the INPUT side and a 35V capacitor on the OUTPUT side. Since it is a "boost" module, this did not make sense. I assumed the manufacturer mistakenly swapped the capacitors before soldering. In fact, the seller's photos show a properly wired board (with a nominal 50V capacitor on the OUTPUT side). However, all five of my modules have a problem with incorrect placement of capacitors. Chinese products. Enough said.
