Overview
The Arduino Portenta C33 brings Portenta-class industrial IoT capabilities at a significantly lower price point. Built around the Renesas RA6M5 ARM Cortex-M33 running at 200MHz with 2MB flash and 512KB SRAM, it supports WiFi, Bluetooth LE, hardware security, and the full Portenta high-density connector ecosystem.
Compatible with both Portenta and MKR carrier boards, the C33 is ideal for IoT gateways, remote control systems, fleet management, and industrial monitoring. It supports Arduino IDE, MicroPython, and Arduino Cloud with OTA firmware updates, real-time dashboards, and secure device management.
The Cortex-M33 architecture includes TrustZone for hardware-based security isolation, making it suitable for applications requiring secure firmware partitioning. It's the most accessible entry point to Arduino's professional Portenta ecosystem.
