SAMD21

The SAM 15x15 is a very small Arduino development board, with the same powerful controller as the Arduino Zero: the SAMD21G18. All I/O pins are used: despite the small size, it has more I/O pins th...

Video To test the SAM15x15 board automatically, I made the tool described here. As you can see, the mechanical construction is very simple. Simple test fixture for PCB probe testing and program...

Intro To use new Arduino boards, we first have to install an appropriate package, which describes the processor and pins. The SAM 15x15 is an expansion of the Arduino Zero board; therefore, insta...
