The Arduino Portenta H7 Lite is a high-performance dual-core development board and the cost-optimised entry point in the Portenta H7 series. It uses the same STM32H747XI MCU as the full Portenta H7, featuring a Cortex-M7 core (up to 480MHz) and a Cortex-M4 core for parallel multi-threaded processing.
With 16MB QSPI flash and 8MB SDRAM, the board provides substantial storage and computing power. It supports the MKR form factor for easy shield expansion, and is compatible with Arduino IDE, STM32CubeIDE, Mbed Studio, and MicroPython. The Lite variant omits wireless connectivity and high-resolution video compared to the full H7, offering a powerful solution where wired communication is preferred.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
