Arduino’s New Portenta C33 IoT SoM Scalable Platform Aimed at Industry

Written by Stephen Vicinanza

Arduino’s new Portenta C33 IoT SoM scalable platform aimed at industry. This latest release from Arduino offers an Internet of Things (IoT) system on a module (SoM) that is packing power, connectivity, and security at affordable prices.

The C33 IoT SoM is part of the Portenta family of SoMs, that provide complete and scalable platforms for IoT edge devices. The latest SoM from Arduino is targeting industrial development. The applications for the SoM include AI devices, IoT gateways, remote control systems, process tracking, and fleet management.

This is an SoM that is aimed at the professional developer, rather than the maker (enthusiast) developer. This is a production-ready IoT platform, Arduino had said at Embedded World, offering an Arduino environment along with other high-level languages such as MicroPython.

The module offers Bluetooth LE and Wi-Fi connectivity and a number of peripheral interfaces that include I2C, CAN, SPI and SAI. The module runs a RA6M5, an Arm Cortex-M33-based microcontroller (MCU) from Renesas, built specifically for industrial IoT.

As for security, Arduino is touting industrial grade at the hardware level for the RA6M5 including Arm’s TrustZone that integrates Secure Crypto Engine 9 (SCE9) that comes with secure key storage.

There is also an over-the-air firmware update capability with Arduino IoT Cloud or other third-party services.

The form factor of the C33 is compatible with Portenta and MKR ranges, and can also be paired with the Nicla module’s smart sensors for quality assurance, in order to catch defects when monitoring production lines.

The Portenta C33 IoT SoM will be commercial available at the end of the Q2 2023, at Arduino’s online store and through authorized distributors. Pre-ordering is available.
