In fact all you need to build an ATSAMD21-based computer on a prototyping board is: In addition it has a USB interface built in, so there's no need for a separate chip to interface to the serial port.Īrduino have designed several excellent boards based on the ATSAMD21, such as the Arduino Zero or smaller-format MKRZERO. However, these boards are an expensive way to use an ATSAMD21 as the basis for your own project, and they probably include many features you don't need. This is an ARM Cortex M0+ processor with up to 256KB flash memory, 32KB RAM, and a 48MHz clock, so it's substantially better equipped than the ATmega328. If you're looking for something more powerful than the ATmega328 in the Arduino Uno a good choice is the ATSAMD21. You can then program the minimal ATSAMD21 computer from the Arduino IDE via the USB port, like any other Arduino board.įor details of the same procedure using the larger 48-pin ATSAMD21G chip see Minimal ATSAMD21 Computer 2. I give two alternative methods of uploading a bootloader to the bare ATSAMD21 chip using the Arduino IDE. Minimal computer on a breadboard, based on an ATSAMD21E. This project describes how to build an ATSAMD21-based computer on a prototyping board using the minimum number of components, and program it from the Arduino IDE:
