I going way out on a limb here, but it shouldn't cause any damage to the RPi if the adapter is working correctly.Lavanyamoorthy wrote: Hi.. I m trying to connect a gps module to raspberry pi 3.. but the gps module has RS232 12V DB9 port and I have a USB-rs232 adapter. So I have a doubt if I can connect the module directly to pi's USB port using the adapter. Or do I require a voltage level shifter or something because the power supply to the gps module is 12V. Will it cause any damage to the Pi if i connect it directly through the adapter. ?
