Arduino Portenta H7 Lite is a cost-down version of Portenta H7 STM32H7 that shaves off a little over $30 of the Arduino Pro board by doing without a wireless module nor USB-C video output and opting for a lower cost Microchip ATECC608 secure element.
Arduino says the new board provides a cost-optimized solution for companies developing high-end industrial machinery, laboratory equipment, computer vision, PLCs, robotics controllers, and mission-critical devices.

The Portenta H7 Lite can be programmed either with the Arduino IDE or MicroPython, with support for Arduino sketches on top of the Arm Mbed OS, Native Mbed applications, MicroPython/JavaScript via an interpreter, and TensorFlow Lite for AI applications.
The latest Arduino Pro board can either be used as a standalone embedded microcontroller board, or as the module for a larger carrier board such as the Portenta Carrier thanks to two 80-pin board-to-board connectors.
You can purchase Portenta H7 Lite now for $72 or 60 Euros on the Arduino store, which compares to $103.40 for the original Portenta H7. Additional information may be found on the product page.
