The third major version of the Raspberry Pi will go on sale Monday, with the $35/£30 credit card-sized Raspberry Pi 3 Model B now sporting a 64-bit processor and embedded Wi-Fi and Bluetooth. In previous versions, the Pi needed USB adapters to get Wi-Fi and Bluetooth connectivity. Raspberry Pi 3 supports 802.11n Wi-Fi (2.4GHz only) and Bluetooth 4.0 without an adapter, freeing up its four USB ports for other purposes.
While the Raspberry Pi 2 released a year ago used a Broadcom system-on-chip with a 32-bit, 900MHz quad-core ARM Cortex A7, the Raspberry Pi 3 upgrades to a 64-bit ARM Cortex A53 that’s also quad-core and is clocked at 1.2GHz.
