I am currently working on a project involving a temperature sensor, previously implemented using a BeagleBone. I have recently transitioned to the Toradex platform and purchased the Mallow Carrier Board with the NXP i.MX 8M Plus Computer on Module. My goal is to replicate and enhance the functionality I had on the BeagleBone using your hardware.
Here are my specific requirements and queries:
Remote Access via SSH:
I need to log in to the board’s terminal remotely using SSH. Could you provide guidance on setting up and enabling SSH access?
GPIO Pin Access for Sensor Integration:
I plan to connect a temperature sensor to the GPIO pins of the Mallow Carrier Board. Could you guide me on how to access and control GPIO pins for hardware integration?
Running Python Scripts for Data Processing:
I will write Python scripts to read data from the sensor and process it for MQTT communication. Could you advise on how to set up the environment for running Python scripts and libraries?
OS Recommendation:
While I see Torizon OS with Docker mentioned in the quick start manual, I would like to understand if this is the best-suited OS for simple hardware sensor integration, or if you recommend an alternative OS.
Power Specifications:
What are the recommended voltage and current requirements for the Mallow Carrier Board?
Basic GPIO Access Examples:
It would be helpful to have a basic example or reference for using the GPIO pins with Python for sensor data acquisition.
Thank you for your support. I look forward to your guidance on getting started with the Toradex platform and successfully integrating the hardware for my project.

Hello!
Thank you for reaching out with your questions about integrating a temperature sensor with the Toradex Mallow Carrier Board. I’m happy to guide you through the process.
Remote Access via SSH:
To enable SSH access, ensure your Mallow Carrier Board is connected to your network. SSH is typically enabled by default on TorizonCore. You can access the terminal using the command ssh torizon@<board-ip-address>, replacing <board-ip-address> with your board’s actual IP address.
GPIO Pin Access for Sensor Integration:
For accessing GPIO pins, you can use the gpiod library in Python. First, ensure the library is installed in your Python environment. You can control GPIO pins by accessing them through the /dev directory in Torizon. Here’s a basic example:
import gpiod
chip = gpiod.Chip('gpiochip0')
line = chip.get_line(23) # Replace 23 with your GPIO line number
line.request(consumer='myapp', type=gpiod.LINE_REQ_DIR_OUT)
line.set_value(1) # Set GPIO high
Running Python Scripts for Data Processing:
TorizonCore is well-suited for running Python applications. You can use the Torizon IDE extension to set up your development environment, which helps manage dependencies and containerize your application for deployment.
OS Recommendation:
TorizonCore with Docker is recommended for your project as it simplifies application deployment and management, especially for Python-based applications. It supports containerization, which is beneficial for managing dependencies and updates.
Power Specifications:
The Mallow Carrier Board typically requires a 5V power supply. Ensure your power source can provide sufficient current, usually around 2A, to support the board and any connected peripherals.
Basic GPIO Access Examples:
The example provided above demonstrates basic GPIO control using Python. For more complex interactions, you can explore further documentation on GPIO and peripheral access.
I hope this helps you get started with your sensor integration project on the Toradex platform. If you have more questions, feel free to ask!
Best regards,
