Hey, I have another doubt though.Is it okay if I simply remove the level shifter only for the transmit(TX) line of the GPS receiver.In other words , is it okay if I directly connect the TX line of the receiver to the MAX232 input line? Because the MAX232 datasheet says that it will recognize voltages as low as 2V on it's inputs. So I simply remove the level shift from 2.8 volts to 5volts...will this modification help in any way?
Accuracy is pretty good...about 10meters indoors...good enough right?
