Hello, i'm stucked at the point that our dear PIC works on 5V, and thus definitely the serin/serout would also generate high and low pulses of 0-5v, while the GSM module which i'm having (SIM508) posses serial transmission module of VMax being 3V...and it's been quoted to use a level converter where necessary, so can anyone help me out with this...
can i use MAX233 in between or would there be any other procedure to follow...

Best Regards
Jamshid Dastur
