GPS logger shield pins question

Post by ensell »

Im looking at building a speedometer. I was planning on using the GPS logger shield, and then send the data to a touchshield slide. However, the touchshield uses pins 2 and 3.

It looks like you can change which pins the gps module uses, however I just wanted to double check before I take the plunge.

Thanks.

Yes. You can wire the gps module to communicate on different pins.

I'll post my question in this thread, since it's related. How many digital and analog pins are still usable and available from the Arduino when you use this shield? I see it only has the one small strip of female header pins on the digital side, and the GPS will take three. It doesn't have any of the female header pins for the analog side.

Pins 10-13 are used for SPI communication with the SD card. The GPS requires 2 pins for serial communication and one to control the power. These are re-configurable. There are 2 optional leds that can be configured to any unused pin. No analog pins are used.

Thanks. So for the other analog and digital pins without the female headers, I guess you just run the wire through the hole in the board?

Yes, but you will need to solder for a good connection. If you prefer not to solder wires to the holes, you can install some female headers cut to length https://www.adafruit.com/products/598
or build the board with stacking headers. https://www.adafruit.com/products/85
