WhereAVR – The Genuine APRS Tracker

Have you noticed that Atmel AVRs have slowly dominated the world? Have a closer and detailed look over the electronic projects on the websites, you’ll find out that over 70 percent of the projects are mainly related with Arduino, Atmel AVR or LED stuffs!

Honestly, if you’re having the interest on building an AVR related project, then you’ve came to the right place! Today, you’re going to develop a small, lightweight with low-power consumption, WhereAVR.


Ok, you must be wondered, “What the heck of this WhereAVR?” Well, to be honest, it’s a low-cost APRS tracker equipped with a full complement of analog and digital I/O.

Talking about APRS, it’s a short acronym, which is mean for “Automatic Packet Reporting System”. Basically, APRS is an amateur radio based system for real-time tactical digital communications of information of immediate value in the local area. The main purpose of APRS is collecting all data, then it will be ingested into the APRS internet system and finally, it distributes the data globally for instant access.

By the way, this WhereAVR also has the ability to decode ax.25 packets and allows for the reception of remote commands without the need for a “real” TNC at all!
