Originally released back in November 2015, Feb 2017 for the Zero W, the Raspberry Pi Zero has finally been upgraded. The Pi Zero 2 W brings the RP3A0 system-in-package so the small form factor of the zero. This chip was originally seen the the launch version of the Raspberry Pi 3. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Raspberry Pi claim the Zero 2 is up to five times as fast as the original Raspberry Pi Zero. The original Pi Zero featured a single core ARM processor clocked at 1GHz.
The Raspberry Pi Zero 2 W is targeting a $15 retail price (we have seen it selling for roughly £13.50 at UK retailers such as Pi Hut). This price is about $5 (£4) more than the original Zero W for a seemingly serious performance boost.
It is not just the CPU that has been upgraded, the wireless connectivity has seen a refresh. Bluetooth 4.2 with Bluetooth Low Energy (BLE) is a boost from the original Zero. We also expect the on-board antenna for the WiFi and Bluetooth to be improved, hopefully increasing the range and speeds of internet connectivity. It should be noted that only one skew of the Pi Zero 2 W is being offered, you can only get one with wireless connectivity unlike the original Pi Zero W/Non-W.
The ports remain identical in both revisions of the board and the inclusion of micro-USB is somewhat disappointing. Raspberry Pi are marketing the Zero 2 as a ‘drop in replacement’ to the original but I am sure many makers will be as annoyed as ever at the micro-USB ports.
