Finally after almost nine months of development we are proud to present Ultratronics v1.0! This 32-bit board will fit the high-end requirements for modern 3D printers. It's based on Arduino Due and several other open-source projects. Most notably this board provides support for 4 extruders, 7 stepper drivers, 4 thermo couples, ethernet, SD and several other functions.
We are still working on some documentation and the design files to be released, so expect updates the coming few weeks. Also we provide a MarlinKimbra firmware, which you can download from the software section. Note that Ethernet support has not been implemented yet and will follow in a new release.
