LibAPRS

LibAPRS is an Arduino IDE library that makes it easy to send and receive APRS packets with a MicroModem-compatible modem.

You can buy a complete modem from my shop, or you can build one yourself pretty easily. Take a look at the documentation in the MicroModem repository for information and getting started guides!

See the example included in the library for info on how to use it!
