Two Arms for the ARM

Extend the versatility of the SAM D20 Board

Small boards bring big benefits when you expand the popular SAM D20 Board used in our ARM course. As of now you can hook up EEC/Gnublin and ECC expansion boards to provide license-free radio links, RS-485, NFC, touch pads, displays, relays, MIDI, 16-bit ADC and many more ingredients for creating new projects with a 32-bit ARM brain. Demo software is included in each case.

What is Elektor Exclusive?

Components

The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
