i am doing a low power mode gps project for msp430fr5739 development board. this board's operating voltage is 3.3 volts and my gps module also can operate with 3.3 volts supplied power. How about effect of logic levels of UART protocol. do i have to use a logic level converter between gps module and msp430 ? or can i directly plug and play Adafuit gps ultimate board with msp430fr5739 development board

  • I agree with @CL., but to "short circuit" the matter why not just measure the output voltage of the pins on the gps module that you are interested in? You will need an oscilloscope. It is unlikely they will be higher than 3.3v. – HeadCode Mar 07 '16 at 16:24
  • thanks i put this question on stack exchange electrical and i found the answer. – engineer nikemen Mar 09 '16 at 14:02
