I've got lots of stock of Octoscrolla and Octoscrolla with real time clock for standalone installs. Both of these are compatible with the original Octoscroller for the Beaglebone Black (BBB). Both come fitted with a 5mm terminal for powering the Octo and BBB from a power supply other than using the BBB power input. I also have bare boards, kits, IDC16 cable and connectors. http://www.hansonelectronics.com.au/?s=octoscrolla&post_type=product I also have lots of stock of my rPi-P10 which allows up to 3 strings of P10 (and other) panels to be connected to a Raspberry Pi. http://www.hansonelectronics.com.au/product/rpi-p10/ There's lots of other boards available and dispatch is usually same day. Overnight delivery to most of Australia and about 7 days to Europe, U.S. or Canada.
