Overview
Max Carrier transforms Portenta modules into single-board computers or reference designs that enable edge AI for high-performance industrial, building automation and robotics applications.
Thanks to dedicated high-density connectors, it can be paired with Portenta X8 or H7, allowing you to easily prototype and deploy your industrial projects.
This Arduino Pro carrier further augments Portenta connectivity options with Fieldbus, LoRa®, Cat-M1 and NB-IoT.
Among the many available plug-and-play connectors there are Ethernet, USB-A, audio jacks, microSD, mini-PCIe, FD-CAN and Serial RS232/422/485.
Max Carrier can be powered via external supply (6-36V) or battery via the onboard 18650 Li-ion battery connector with 3.7V battery charger.
Key benefits include:
- Easily prototype industrial applications and minimize time to market
- A powerful carrier exposing Portenta peripherals (e.g. CAN, RS232/422/485, USB, mPCIe)
- Multiple connectivity options (Ethernet, LoRa®, CAT-M1, NB-IoT)
- MicroSD for data logging operations
- Integrated audio jacks (line-in, line-out, mic-in)
- Standalone when battery powered
- Onboard JTAG debugger via micro-USB (with Portenta H7 only)
Prototyping on Portenta projects
The Arduino Portenta Max Carrier is designed to assist developers with their prototypes by exposing the main peripherals of the high-density connectors of the Portenta family boards (H7 and X8). It allows for easy debugging through the JTAG connector and for inspection of the CAN lines through the pins. At the same time, it is the right tool to test Ethernet connectivity as well as to extend connectivity options (CAT-M1, NB-IoT and LoRa®).

As Jallson Suryo discusses in his project, adding voice controls to our appliances typically involves an internet connection and a smart assistant device such as Amazon Alexa or Google Assistant. This means extra latency, security concerns, and increased expenses due to the additional hardware and bandwidth requirements. This is why he created a prototype based on an Arduino Nicla Voice that can provide power for up to four outlets using just a voice command. Suryo gathered a dataset by repeating the words “one," “two," “three," “four," “on," and “off” into his phone and then uploaded the recordings to an Edge Impulse project. From here, he split the files into individual words before rebalancing his dataset to ensure each label was equally represented. The classifier model was trained for keyword spotting and used Syntiant NDP120-optimal settings for voice to yield an accuracy of around 80%. Apart from the Nicla Voice, Suryo incorporated a Pro Micro board to handle switching the bank of relays on or off. When the Nicla Voice detects the relay number, such as “one” or “three," it then waits until the follow-up “on” or “off” keyword is detected. With both the number and state now known, it sends an I2C transmission to the accompanying Pro Micro which decodes the command and switches the correct relay.
