I was doing my own DIY Arduino Board, and I was confused to what microprocessor should I use in making the Arduino MKR Zero board. The provided microcontroller from the schematic diagram is ATSAMD21G18A-48, but whenever I search it on the market, suggested microprocessor are ATSAMD21G18A-AU, ATSAMD21G18A-AF, ATSAMD21G18A-AFT, ATSAMD21G18A-AUT, ATSAMD21G18A-MUT, ATSAMD21G18A-AZT and etc. I was so confused and I don’t know much about these stuffs!
Send help. Thank you so much!!!
