[2018-07-20] The seller contacted me to offer a replacement for these MCU boards. That's good customer service and I think I just had an anomaly in the batch I received. If anything goes wrong I will come back to give an update but HiLetgo is doing great at the moment. [Original Review] Poor quality of many of my parts. I bought a few of these and have most of them. manufacturing defect. On one of these, I had to readjust the solder on the USB connector because it didn't make contact when the cable was pulled over it. The other cannot be repaired because the legs of the UART chip were bent when it went through the surface mount soldering process. There is no way it could have been fully QA tested or visually inspected with this bug. Not charging or blinking. The photo here is after I removed the large blob of solder from the edge of the part. Too bad they didn't have a slightly better QA
