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.

Portenta H7 Lite has the same board layout as its older brother, and the main differences are the removal of several chips and modules including Murata 1DX module and antenna, the MIPI to USB-C/DisplayPort converter and corresponding level shifter, NXP Crypto chip (replaced by Microchip ATECC608 on the bottom of the board), plus some other passive components.
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.
