The Raspberry Pi Zero W offers all the benefits of the Pi Zero v1.3, but with one big difference – built-in WiFi
More specifically, this giant upgrade is the addition of a BCM43143 WiFi chip BUILT-IN to your Raspberry Pi Zero – just like the Pi 3! No more pesky WiFi adapters – this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution.
This is the slimmest, most pared down Raspberry Pi to date. It’s kind of like the little cousin to the Pi 3 – with just a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, similar to the Pi A+ and B+.
The Pi Zero W keeps the same shape, connectors, and mounting holes as the Pi Zero v1.3. 99% of cases and accessories will still be fully compatible.
