If you don’t have an Arduino board with a SAMD21 uC, you can find out more about them here. Posted in Arduino Hacks, News Tagged adc, analogRead(), arduino, SAMD21. Post navigation.

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

For more information on the new Arduino Prototyping Set and Bootloader Shield jump over to the Kickstarter website for details and to make a pledge from $18.

This new Arduino Zero board works with no less than an Atmel SAMD21 MCU. This architecture rolls with a 32-bit ARM Cortex M0+ core, enabling the Arduino Zero to far outperform its predecessor.

Specifications of the SAMD21 M0+ Arduino-compatible board : Microcontroller: Atmel ATSAMD21G18A ARM Cortex M0+ Clock speed: 48 MHz Operating voltage: 3.3V I/O pin limits: 3.3V, 7 mA ...

The Arduino Zero is based on Atmel's SAMD21 MCU. The SAMD21 MCU comes with 256kb of flash and 32kb SRAM in a TQFP package and is compatible with a 3.3V Shield that conforms to the Arduino R3 Layout.
