Hi guys i am using quectel l80 gps module in my project and i used tinygps library but i cant communicate with the sensor using arduino.....
When i looked into datasheet it stated that module will works only on cmos level...can u plzz send me external circuit that converts CMOS TO TTL and CMOS TO RS232 .....
I looked at this module some time ago and without there are other variants it requires a 3v supply, ground, TX and RX connections.
RX to TX and TX to RX between arduino and GPS.
Unlike the globaltop and other modules I do t think it has a led indicator for obtaining a fix.
Much more than 3v applied to it is likely to kill it.
Best of luck getting it going
Regards
