Microcontroller
Arduino Portenta H7
An industrial-grade dual-core Arduino for edge-AI and industrial-IoT products, used as the reference platform for Arduino's PRO ecosystem with vision, motor-control, and secure-boot workloads split across two cores.
Processor
STM32H747XI dual-core Cortex-M7 @ 480 MHz + M4 @ 240 MHz
Logic
3.3 V GPIO
Power
USB-C, VIN, or Li-Po 3.7 V with onboard charger
Format
MKR-style footprint plus two 80-pin high-density connectors
Check before wiring
- Total I/O current is limited to 140 mA summed across all pins, 20 mA per pin — easy to exceed on the high-density connectors (official pinout, rev 2021-10-26).
- High-density connectors carry FORCE_BOOTLOADER, BOOT_SOURCE, and POWER_ON_REQ pins that carrier boards must handle or the module will not boot as expected.
- Ethernet, USB-HS ULPI, and MIPI signals share high-density pins with GPIO/timer functions — consult the full mux table before designing a carrier.
- Documentation uses CIPO/COPI naming; legacy MISO/MOSI example code must be remapped.

This board has official references linked, but its in-app connector map still needs a source-backed import.
Why it matters
- Asymmetric dual-core lets one core run an RTOS/ML workload while the other handles I/O.
- 22 breadboard-friendly pins plus two 80-pin high-density connectors for carrier boards.
- USB-C, Li-Po charging with fuel-gauge input, and onboard Wi-Fi/Bluetooth.
- Official pinout PDF documents every pin including the high-density connectors.
