Thank You for the confirmation.

 

Ajish,
What you are suggesting is that the USB to Uart(ttl) outputs are not sufficient to drive communication between the USB modem and the LPC 1769 ?

 

I/O pins of the LPC 1769 are 3.3/5 volts tolerant, are you saying that the output volltage of the USb to Uart converter maybe too high and cause damage the MCU ?
 

 

 

Apologies, as i am new to this assignment.
