I am using Adafruit's Ultimate GPS unit. All is going great, and with Vcc, Gnd, Tx, and Rx pins setup the Rasp Pi and GPS unit are talking to each other. Moving on from an early prototype stage, I would like to make use of other pins. These would include the EN and FIX pins. Focusing on the EN pin, I would like to enable and disable the GPS unit from a GPIO pin of the Rasp Pi. At the following page (https://learn.adafruit.com/adafruit-ult ... ps/pinouts) it states:
This confuses me, and I don't want to leave the EN pin floating. Can I simply connect the EN pin to a GPIO pin to toggle the GPS unit on and off without adding my own resistor? If an external resistor is required, what would a circuit diagram look like between the GPS unit and the Rasp Pi?EN is the Enable pin, it is pulled high with a 10K resistor. When this pin is pulled to ground, it will turn off the GPS module.
Thanks in advance!!!
