CPUs ( CPU-type / RAM / Program memory):
CUL V1/V2: at90usb162 / 0.5 kB / 16 kB
CUL V3: atmega32U4 / 2.5 kB / 32 kB
CUN: at90usb64 / 2.0 kB / 64 kB
CUNO: atmega644p / 2.0 kB / 64 kB
CUR V1: at90usb128 / 4.0 kB / 128 kB
CUR V2: at90usb64 / 2.0 kB / 64 kB
From the program memory 4kB is used by the USB-Bootloader, and 4kB by the LUFA USB library.
culfw supports following RF protocols:
When configured as an RFR (RF-Router) client, then a CUL plugged into a wall socket can communicate via high-speed RF to the base, while serving all the SlowRF protocols.
CUNO: OneWire and InfraRed support.
