The Arduino Uno's design has remained almost unchanged for more than a decade. It still uses the venerable ATMega328 processor, which is just as old. The Arduino Zero was released in 2015, based on the SAMD21 processor, an ARM Cortex-M0+ which was more expensive and only ran at 3.3V, instead of the 5V standard of most other Arduino boards.
In 2015, Atmel (now Microchip) released the SAMC line of processors. This series of processors is based on the ARM Cortex-M0+ core, can run at 3.3V or 5V, and even includes two onboard CAN controllers, making it perfect for both industrial applications and hobby applications.
The FortyTwo Systems UNO is the first Arduino-compatible board to feature this new processor. The board keeps the same form factor and pulls much of its electrical design from the Arduino UNO.
Project status:
- Toolchain available and tested for Windows x86, Mac, Linux ARM32. Other arches coming very soon.
- PCB designed and tested.
- Bootloader written and tested.
