The Arduino Portenta H7 is Arduinos newest microcontroller. The H7's main processor is the dual core STM32H747 including a Cortex M7 running at 480 MHz and a Cortex M4 running at 240 MHz. The two cores can communicate with each other over a Remote Procedure Call mechanism that allows calling functions on the other processor.
Both processors share all the in-chip peripherals and can run:
- Arduino sketches on top of the Arm® Mbed™ OS
- Native Mbed™ applications
- MicroPython / JavaScript via an interpreter
- TensorFlow™ Lite
The Portenta H7 also includes an on-chip GPU that allows you to connect an external monitor to build your own dedicated embedded computer with a user interface. The Portenta also has two 80 pin high density connectors at the bottom of the board that allows you to attach extentsion boards like the Vision Shield. Furthermore the Portenta H7 also features a Murata 1DX, which is a high performance chipset which supports WiFi 802.11b/g/n + Bluetooth 5.1 BR/EDR/LE up to 65Mbps PHY data rate on WiFi and 3Mbps PHY data rate on Bluetooth.
