I had to desolder the female headers on that red USB adapter board because of this problem. And just my luck the female headers I bought are the very same type installed by the manufacturer on their board! So soldering the new headers was anxiety-provokingly fiddly.
|The gaps within each pin of the female header allow solder to wick into the inner recesses and clog the socket, thus rendering the header unusable--boards with male headers cannot be plugged in|
|A new 2-mm female header just soldered in place|
|In contrast is this 2.54-mm (0.1") female header|
