SAMD21G Arduino compatible development board
The website www.avdweb.nl contains many technical articles, for instance, a DIY spot welder, Arduino libraries and e-bike electronics. Here we will highlight the new SAMD21G18 development board.
The SAM 15×15 is an Arduino development board of 28x28mm, which can be reduced to 15x15mm, with the same powerful controller as the Arduino Zero: the SAMD21G18. Despite the small size, it has more I/O pins than the Arduino Zero. Due to the very small dimensions, it will fit easily into all embedded electronic projects, even in microdrones.
