This guy looks very exciting. Any thoughts?

expensive, overpowered, not enough pins for the power it has.

The also overpowered NUCLEO-F429ZI (http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-nucleo/nucleo-f429zi.html) is about 20€ + tax + shipping (AliE. ~40€), but at least has enough pins for now - even if not directly compatible with MEGA/DUE shields.

I have a ShieldBuddy and will look at implementing a HAL for it, but that would probably be after Re-ARM. The ShieldBuddy runs at 5V, so it might be possible it can run with RAMPS 1.4. ShieldBuddy is probably too expensive except for some niche applications.

There are lots of cheap CPU boards like Nucleo, but there is really no point considering them if there is no printer shield for them.

Hi, we have been approached to port the Marlin printer app onto the Shieldbuddy. This looks feasible but there is some AVR assembler code to change into Aurix.

Unlike the Nucleo the ShieldBuddy price is not subsidised by the processor manufacturer. However as the volume goes up, the price will go down!

We could put an extra row of pins inside the Arduino connectors if that would make it more useful.

Btw. The Shieldbuddy is GBP79 or Euro99!

I know cnc-shield is not as convenient as a RAMPS or other dedicated 3D-printer-board, but for a developer it works and provides a lot of freedom, if you have a bit of space on the desk.
