Today we review the long-awaited NORVI Arita controller on the ATmega2560. It is long-awaited because most manufacturers, in my opinion undeservedly, ignore the wonderful ATmega2560 microcontroller, and where necessary and, most importantly, where not needed, use ESP32. ATmega2560 doesn't have Wi-Fi, but it does have "oak" 5V logic, 4 hardware Serials (on separate pins), 53/69 (!) GPIOs, 16 analog inputs, 15 PWM ports, 4KB "honest" EEPROM memory, 40 mA pin load capacity and other practically useful amenities. Against this background, the ESP32 with its ten rickety GPIOs looks like some kind…
