This project is an Open Source hardware board with spring terminal blocks that exposes all pins of the Arduino Pro board, for development purposes.
I regularly make several of these boards, if you are curious, let me know (rufus31415@gmail.com). I only make them if enough people are interested.
It is approximately : shipping + 50€ / piece.

Here is a short video detailing the steps to make this card yourself.
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.
- 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
