We are excited about the new Raspberry Pi 3 that was just released. Its use of a more powerful ARM Cortex A53 processor, Wifi and Bluetooth will make it even easier to build systems. Some have been ordered already for coursework!
The processor even uses Big.LITTLE technology from ARM. This is now used on some phones/tablets as it means a lower power consumption overall. It does this by pairing each core with a smaller less power hungry core and using them when full performance is not needed.
