Arduino has long used Atmel (now Microchip) 8-bit AVR architecture microcontrollers. The ATmega328P, ATmega32U4, and ATmega2560 have been discussed here. Arduino no longer is “in bed” with Microchip, but there are two other Microchip microcontrollers used in Arduino boards, the ATmega4809 and the SAMD21. Both of these are favorites of mine. ATmega4809 The ATmega4809 is …

There are some Arduino boards that have microcontrollers only used in one board. While the Arduino Framework, the library of functions, attempts to keep all boards compatible, at the lowest level there are differences. These boards because of their unique microcontrollers will generally have the lowest compatibility and potentially the most problems in their use. …
The Arduino website lists 27 different board models, with 5 currently marked as “sold out”. We will assume for these articles that the ones that are sold out will return. Of the 27, three use the very old, but not quite original for Arduino, ATmega328P microcontroller.. Two of these are the still popular, and widely …
