Arduino Uno R4
L'Arduino Uno R4 est proposé en deux versions:
- Arduino Uno R4 Minima
- Arduino Uno R4 Wifi
Cette carte est équipée du processeur ARM Cortex-M4 32 bits Renesas RA4M1, elle offre une augmentation importante de la puissance de traitement, de la mémoire et des fonctionnalités.
La version WiFi est livrée avec un module WiFi ESP32-S3 en plus du RA4M1.
