Turn your Arduino into a powerful radio transceiver!

Now in stock and shipping!

HamShield lets your Arduino talk to far away people and things using powerful amateur radio bands! Best of all, the hardware and software is open source! Launched on Kickstarter and available today! Voice and packet radio data are supported in our library.

This is the HamShield only. No power connector or antenna is provided. This uses a standard SMA antenna, which some of our users may already have. Since this is an amateur radio kit, soldering of the SMA antenna and headers are required (but we promise it's easy!). 

We sell a couple of great antennas, where some of the proceeds go to a good cause: Amateur radio education.
