Raspberry Pi Zero WH

5.9/10verdict: wait for deal

The Raspberry Pi Zero WH is for people who want a small, low-power board with GPIO ready to use straight away. It suits single-purpose projects that need Wi-Fi, Bluetooth and header-based add-ons rather than much processing power. It is not aimed at anyone who needs wired networking, fast storage or several services running at once.
