Title: Axon And GPS
Post by: Hanoush on February 10, 2009, 10:26:57 AM

I was wondering if I can use Axon with this GPS http://www.robotshop.ca/usglobalsat-em-406-gps-module.html (http://www.robotshop.ca/usglobalsat-em-406-gps-module.html)
I am not sure if Axon supports Serial interface (TTL) ?

The TTL interface is done through UART.

The Axon has three UARTs plus a fourth connected to USB. You won't find this on any other microcontroller on the market (that's easy to use).

That being said, you should check out this link for GPS too:

I've been thinking of buying this guy to use on an Axon:

Just four pins: ground, Tx, Rx, and power

Hi Hanoush,

I think you can use this GPS with the Axon as it has 4 UARTs: the USB Port, and 3 TTL ports. They are arranged on the board like in the attached image. Just connect the GPS to one of the 3 TTL UARTS connections, and you should be good to go!

Good luck :)
