Arduino Portenta C33 System-on-Module (SOM) IoT Board
Arduino Portenta C33 SOM: A cost-effective IoT module with Wi-Fi, Bluetooth 5.0, Ethernet & secure element. Ideal for professional IoT projects.
The Arduino Portenta C33 is a powerful, cost-effective System-on-Module (SOM) engineered for professional Internet of Things (IoT) applications. Based on the Renesas® R7FA6M5BH2CBG microcontroller featuring an Arm® Cortex®-M33 core running at 200MHz, it delivers robust processing performance for connected devices. It shares the identical form factor with the Portenta H7, ensuring full backward compatibility with the entire Portenta family of shields and carriers via its high-density connectors, offering a seamless upgrade path for existing designs.
This module is packed with essential features for modern IoT development, including 2MB of flash memory, 512KB SRAM, and an additional 16MB QSPI flash for data storage. Integrated wireless connectivity is provided by a 2.4GHz Wi-Fi® (802.11 b/g/n) and Bluetooth® 5.0 module (ESP32-C3-MINI-1U), while a dedicated Ethernet PHY transceiver (LAN8742AI) enables wired network options. Security is built-in with an IoT-ready secure element (SE050C2), crucial for device authentication and data protection.
