For questions specific to the Pi-Zero W (with WiFi and Bluetooth)

The Pi Zero W adds WiFi and Bluetooth to the existing Pi Zero.

The Raspberry Pi Zero

  • A 1 GHz single-core ARM11 CPU
  • 512 MB of RAM
  • On-board Wireless LAN - 2.4 GHz 802.11 b/g/n (BCM43438)
  • On-board Bluetooth 4.1 + HS Low-energy (BLE) (BCM43438)
  • microSD card slot
  • Mini-HDMI socket
  • Micro-USB sockets (for power and data)
  • Unpopulated 40-pin GPIO header and composite video header
  • a "mini" CSI-2 camera interface - which is the same as used for the Compute Module I/O Board {needs a mini-to-standard flexible connector to use with RPi camera modules}.
  • Form factor 65 mm x 30 mm x 5 mm
