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, cost-effective board built around the Renesas RA6M5 microcontroller. It features a single-core Arm Cortex-M33 running at 200 MHz, onboard Wi-Fi and Bluetooth Low Energy via an ESP32-C3 module, and 10/100 Ethernet support. Designed for IoT gateways, edge applications, and robust automation requiring reliable connectivity and processing power, it is compatible with the Portenta and MKR ecosystems.

Compatibility
The Portenta C33 works with the Arduino IDE, Arduino Cloud, and MicroPython via Arduino Labs. It shares the MKR-style pin header, so it is compatible with MKR shields and carriers. It communicates with 3.3 V sensors and actuators over I2C, SPI, or UART. For 5 V devices, use level shifting — all I/O operate at 3.3 V.
Wiring Notes
Power the board via the USB-C connector with a standard 5 V supply, or through the VIN pin. All I/O pins operate at 3.3 V — do not connect 5 V signals directly. When using Ethernet, connect a supported PHY module to the appropriate connector.
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 the MKR-style pin layout and 3.3 V logic. Use MKR shields and carriers, or level shifters for 5 V peripherals.
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. Flash the firmware and use an IDE like Thonny or Arduino Lab for MicroPython.
