About Arduino PRO Portenta H7 Carrier Board 😀

This project is an Open Source hardware board with spring terminal blocks that exposes all pins of the Arduino Pro board, for development purposes.

Order

I regularly make several of these boards, if you are curious, let me know ([email protected]). I only make them if enough people are interested.

It is approximately : shipping + 50€ / piece.

Arduino Uno shield compatible 👍

About Arduino PRO 🌈

Arduino PRO (https://store.arduino.cc/portenta-h7) is a new Arduino MKR board with dual core processor, USB-C, Display port, Ethernet, Wifi, Bluetooth, ... It can run Arduino Sketches, Javascript, Python or TensorFlow models. It has two 80 pins connectors. All pins are available on this carrier board.

Modifications

• v1.1 :
  • Move hight density connector J1 from X=-20mm to X=-20.2mm
  • Delete the 4 external pins for hight density connector
  • Enlarge the footprint of high-density connectors (pin width from 25.98mil to 30.98mil)
  • Enlarge to 0.28mm track width for GND, 3.3V, VSYS
  • Link pin GND 54 of J1 to Shield header GND
