Hey,
I bought a LC02 module off Ali Express https://a.aliexpress.com/_EQaxyze. The strange thing is that the laser markings on the package have been removed.
It seems to send data but does not seem like NMEA. Tried all available baudrates.
What VCC and I/O voltages are you using?
Just tried another USB serial converter. It seems like the first one was broken. Looks much better now
