R4WIFI-ENTRY
UNO R4 WIFI + ENTRY CLOUD
The Arduino UNO R4 WiFi features a 32-bit Renesas RA4M1 microcontroller with a 48 MHz Arm® Cortex®-M4 processor and an integrated ESP32-S3-MINI-1-N8 Wi-Fi® module. It offers expanded memory compared to previous models, with 256 kB flash, 32 kB SRAM, and 8 kB EEPROM. The board operates at two voltage levels (5V for the microcontroller and 3.3V for the Wi-Fi module), with a logic-level translator facilitating communication between these components. This design enables enhanced wireless connectivity and processing capabilities for IoT and embedded system projects.
