The Arduino Uno R4 Minima seemingly has a purpose of eventually replacing the Arduino Uno R3. It’s a 5 volt board with the same form factor as the earlier Uno that seemingly offers more performance (speed and memory capacity) at a 25% lower price point. People are finding flaws in that it has lower current …

The EEPROM library (https://docs.arduino.cc/learn/built-in-libraries/eeprom) has functions for reading and writing single bytes but no function for erasing. The EEPROM in the AVR microcontrollers are capable of erasing and writing single bytes and 100,000 erase/write cycles in a location is the design maximum before the EEPROM will wear out. To maintain compatibility, the EEPROM functions in …
Today I got the new Arduino Uno R4 boards in the mail. This includes the Minima and Wifi models, but this post will just concern itself with the Minima. The R4 Minima is much less expensive than the R3, but still a bit more than a good R3 clone like the Elegoo. You can see …
