The original Raspberry Pi Zero was a game-changer for inexpensive computers, offering a full-fledged for just $5. The biggest problem was the lack of WiFi. The Raspberry Pi foundation have now fixed that, unveiling the new Zero W with both WiFi and Bluetooth.
The lack of built-in WiFi meant any project requiring wireless Internet would require a USB hub, and enough additional cost one might as well get a Raspberry Pi 3. Recognizing this, the Raspberry Pi foundation figured out how to squeeze WiFi hardware on the same exceedingly tiny computer footprint. The implementation uses the same Cypress CYW43438 wireless chip as Raspberry Pi 3 Model B to provide 802.11n wireless LAN and Bluetooth 4.0 connectivity.
The Raspberry Pi Zero W specs are:
- 1GHz, single-core CPU
- 512MB RAM
- Mini-HDMI port
- Micro-USB On-The-Go port
- Micro-USB power
- HAT-compatible 40-pin header
- Composite video and reset headers
- CSI camera connector
- 802.11n wireless LAN
- Bluetooth 4.0
Also introduced is a line of standard cases for the Zero W. Like the Raspberry Pi 3 official case, these snap together requiring no tools. The choice of tops includes one with a hole for the camera, and another with access to GPIO pins.
