Arduino MEGA 2560 R3 for Robo R1+ | Arduino Clone
ZYLtech MEGA 2560 R3 Board Atmega16u2/Atmega2560 for Arduino w/ Free USB Cable
We have found that this Arduino clone will work with the R1/+ 3D printer as a replacement for the Robo Arduino board. However it does not have the extended USB port, so once mounted in the printer, you will need to push the USB plug a little further into the printer housing to connect the cable (see picture).
You will need to load the R1 firmware onto this board. Instructions for doing this may be found through the link below.
1x Atmega16u2/Atmega2560 Board
1X 20" shielded USB cable
