Hello friends, I hope you all are doing great. Today, I am going to share the Arduino UNO R4 Minima Library for Proteus . The UNO R4 Minima is the UNO of today: the same size and headers as the UNO R3 you know, but with a 32-bit Renesas RA4M1 (Arm Cortex-M4 at 48 MHz), 16 times the RAM, USB-C and a 24 V input. With this library the Minima runs your Arduino sketch in Proteus 8.5.
