Arduino Portenta C33 – Renesas RA6M5 Board with Wi-Fi/BT
Arduino Portenta C33 – Renesas RA6M5 with Wi-Fi/Bluetooth and Ethernet
The Arduino Portenta C33 is a high-performance industrial-grade board built around the Renesas RA6M5 microcontroller. It features a dual-core ARM Cortex-M33 clocked at 200 MHz, onboard Wi-Fi through an ESP32-C3 module, Bluetooth 5.0 Low Energy, and 10/100 Ethernet via an external PHY. This board is designed for demanding IoT gateways, AI at the edge, and robust automation systems requiring reliable connectivity and processing power.

What You Can Build With This
- Industrial IoT sensor node for monitoring temperature, vibration, and equipment status with cloud dashboards.
- Real-time data logger with SD card storage and remote access over Wi-Fi or Ethernet.
- Smart home gateway bridging BLE sensors to home automation platforms via MQTT.
- Edge AI camera system using an external module for object detection or anomaly classification.
Compatibility
The Portenta C33 works seamlessly with the Arduino IDE, Portenta family shields, and carrier boards like the Portenta Breakout. It communicates with most 3.3 V sensors and actuators over I2C, SPI, or UART. For Arduino Uno shields, a level shifter is required due to the 3.3 V logic. It is fully supported in Arduino IoT Cloud and compatible with MicroPython via Arduino Labs.
Wiring Notes
Power the board via the USB-C connector using a standard 5 V adapter or computer port. All I/O pins operate at 3.3 V — avoid connecting 5 V signals directly. The onboard LDO can supply up to 500 mA for external peripherals. When using Ethernet, connect a supported PHY module to the ESLOV header.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno shields?
No, the Portenta C33 uses a different pin layout and 3.3 V logic. Use Portenta-specific shields, a breakout board, or level shifters for 5 V shields.
Does it come with a USB cable for programming?
A USB-C cable is not included. Use any standard USB-C data cable to connect to your computer for programming and power.
Can I run MicroPython on the Portenta C33?
Yes, MicroPython is supported through Arduino Labs. You'll need to flash the firmware and use an IDE like Thonny or Arduino Lab for MicroPython.
