Infobox info icon.svg.png Not Open Source

This design claims to be Open Source, but was found to not comply with RepRap's lowest common denominator about what Open Source is:

Comes with sources sufficient to make a copy.

In particular, at least these item(s) were found to be missing:

  • Board layout.

There might be more items missing.

If you want to help improving this design, please find source files for these missing items and upload them to this wiki or link to the repository containing them. Then re-verify wether the above statement is true. In case you can answer this with a "yes", remove this message.

Infobox info icon.svg.png This page is flagged as Advertising.

This page is found to exist for the sole purpose of Advertising, This page will eventually be removed.

Reason: questionable sources, does not comply with lowest common denominator of opensource

Proposed removal date: 12/03/2015

Funny side note: the makers of this board did choose a CC licence, but it's a surprise to them that they're expected to actually comply with this licence.

RADDS is the abbreviation of „RepRap Arduino-Due Driver Shield“ and is similar to the commonly used RAMPS 1.4 by Johnny Russel, but leverages Arduino Dues' much higher computing power.



The RADDS-Board provides the following connectivities:

  • 6 Steppers: e.g. 3 axis and 3 extruders (2 of the driver sockets are fitted with 2pin strips)
  • 6 High-current loads: e.g. 1 heatbed, 3 hotends and 2 fans
  • SD-Card(micro-sd-slot onboard, optional external SD-slot)
  • Standard LCD(5V) with 4x20 characters (HD44780 compatible)
  • Rotating encoder
  • 6 endstops
  • 5 thermistors and a ADC
  • 3 servo motors
  • I2C, SPI, CAN, DAC, RS232 and 8 digital-pins available via pin strips
  • 1 Bluetooth to Serial (rf-transceiver bluetooth-modul hc-06 rs232)
  • 1 Thermocoupler(AD8495)

Additional Features:

  • Control-LEDs for loads and operation voltage
  • Catch-diodes at the FETs
  • Car-fuses instead of thermofuses
  • Operation with 12/24V possible
  • Heatbed-current can be up to 15A without a heatsink
  • Premium screw terminals

RADDS and 24 Volts

If the RADDS board is powered by 24 V, then D1 three Zener diodes with about 4 V and 1.3 watts can be soldered instead of a diode, so that the Arduino Due is still powered by the RADDS board with power can. The Zener diodes "wasted" then about 12 V and the Due come to only 12 V, which corresponds to the specification. It is important that the diodes are reverse biased, that is, they must be "upside down" installed. See picture (click to enlarge).



Zur Zeit nur Unterstützung in Repetier-Firmware vorhanden. Wer mag kann es gerne für Marlin anpassen. Marlin4due
