Arduino Portenta C33 System-on-Module (SOM) IoT Board
Arduino Portenta C33 System-on-Module with Arm Cortex-M33 at 200MHz, Wi-Fi, Bluetooth 5.0 and Ethernet PHY for professional IoT applications.
Arduino Portenta C33 System-on-Module (SOM) IoT Board is a System-on-Module built around a 200MHz Arm Cortex-M33 microcontroller for professional Internet of Things applications. It shares the same form factor as the Portenta H7, providing backward compatibility with the Portenta family of shields and carriers through its high-density connectors.
Overview
The Renesas R7FA6M5BH2CBG microcontroller delivers processing performance for connected devices. The module includes 2MB of flash memory, 512KB of SRAM and an additional 16MB QSPI flash for data storage, making it suitable for IoT development projects that require onboard storage.
Connectivity and Security
Wireless connectivity is provided by a 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 module (ESP32-C3-MINI-1U). A dedicated Ethernet PHY transceiver (LAN8742AI) enables wired network options. An IoT-ready secure element (SE050C2) is included for device authentication and data protection.
