The Raspberry Pi Zero is a fantastic, miniature version of the Raspberry Pi that shrinks the board down to about the size of a stick of gum, but one problem with it is the lack of wireless features. The Raspberry Pi Zero W is a new version that packs in Bluetooth and Wi-Fi for a low price. The new Raspberry Pi Zero W offers all the benefits of the Pi Zero v1.3, but with one big difference – built-in WiFi and Bluetooth for a low price!
The difference between the original and v1.3 was easy to see because the camera connector was added to one end of the board. The difference in Zero W is more subtle. You can see pretty easily that a couple of new components have been added in the same area where the camera connector is located.
This is the slimmest, most pared down Raspberry Pi to date. It's kind of like the little cousin to the Pi 2 - 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 best part about all this is that 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 with both the Pi Zero W and v1.3.
Here’s a breakdown of the full specs on the Raspberry Pi Zero W:
- 1GHz, Single-core CPU
- 512MB RAM
- Mini HDMI and USB On-The-Go ports
- Micro USB power
- HAT-compatible 40-pin header
- Composite video and reset headers
- CSI camera connector
- 802.11n wireless LAN
- Bluetooth 4.0
The key feature of the Raspberry Pi Zero W V1.3 was to support the camera serial interface (CSI connector) which used to be equipped on high-end Raspberry Pi. Thus, Pi Zero w began to be able to connect with cameras.
Indeed, numerous Raspberry Pi users choose to add Raspberry Pi cameras to have various applications. It was a shame that Pi Zero 1.2 cannot access cameras, but 1.3 supports the function again.
However, Pi Zero 1.3 still does not support DSI interface. Per the general usage, Raspberry Pi users use CSI interface more frequently than DSI interface. That might be the reason why Pi Zero 1.3 regained the CSI support first.
The steps to connect Raspberry Pi Zero and the camera module are given below
1. Connect your camera module to the CSI port on your Raspberry Pi, this is the long thin port adjacent to the HDMI socket.
2. Gently lift the collar on top of the CSI port.
- Insert the wider end of the adapter cable with the conductors facing in the same direction as the camera’s lens.
- Finally, attach the adapter to the Pi Zero by gently lifting the collar at the edge of the board and inserting the smaller end of the adapter with the conductors facing the back of the Pi Zero.
Your setup should look something like this:
