Are there any disadvantages like increased power consumption etc. of simply pulling CS (Chip Select) to ground? My guess is that CS is only important when having multiple displays on the same bus. I want to reduce the number of signal lines to 6 or below so the display can be controlled by an ATtiny...

This is a great little GPS module. Sadly the pcb designers forgot to add a 5th pin to the connector for an important feature: The module provides a GPS locked high precision timer output (between 0.25Hz and 1KHz for the NEO-6M) at pin3 (TIMEPULSE). This is ideal for using the module as timebase or f...
