Well this is disappointing: no space left on device

Raspberry Pi 3 installed in your R2 can accept any card that is formattable as FAT32, I have one attached to my R1 and another attached to an SLA printer and both have a 32GB card. Robo does what everybody else with an rPi and uses an image that will fit on the smallest card readily available.

Longer explanation:
When applying the RoboOS image the space allocated on the SD card is approximately equal to the size of the original image. It repartitions the card into several volumes only the first of which (/boot/) retains the FAT32 file format. Then creates Linux partitions (formatted EXT4) for all remaining partitions up to the limited size of the original image. If you shell into the rPi using ssh, which is enabled in the RoboOS image, you can use raspi-config to expand the linux partition to fill the remaining unallocated space on the SD card. You can use the following command in the ssh window:

Code:

sudo raspi-config

You can use a PC application such as Putty or Bitvise SSH Client to attach to the rPi via the secure shell. There are plenty of YouTube video that can walk you through step by step on how to expand the rPi file system.
