Buy the Enigma touch
The Enigma touch comes assembled & tested. Either buy a single machine ($185), or order a two-machine pack ($295),
to start communicating relatively securely with a friend :-)
NOTE: As shipped, the Enigma will be powered through a USB-C cable. If you wish, you can also plug in a standard LiPo battery pack, there already is an adhesive patch on the board that is meant for that. Sadly, international shipping rules make it impossible for us to include the $10 battery in the kit. But you can easily buy one here (US) or here (Europe).
