If you didn't think that the Raspberry Pi Zero could possibly get any better, then boy do we have a pleasant surprise for you! The new 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 (BLE support is still in the works, software-wise).
At first glance, the Pi Zero W looks just like the Raspberry Pi Zero v1.3 we know and love. But when we started to think of the added convenience of not having to worry about hooking up a WiFi dongle or Ethernet cable - and what a well-chosen set of accessories could add - we realized the appeal. And then we saw the price...could it be true? Yes!
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 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 - though if you have a case with a metal top there might be some WiFi chip difficulties.
Please note - even though there's built-in WiFi, the Pi Zero W is quite minimal and requires a few accessories to turn it into a computer! At a minimum we recommend:
- A good quality 5V power supply - Either a 5V 2A with cable or combine a 5V 1A power supply and a Micro B USB cable - this will allow you to power the Zero from a wall adaper. It is not suggested to power the Zero from a computer USB port as the voltage often sags and can cause SD card corruption!
- 4GB+ SD Card with Operating System - You can grab a ready-to-go Raspbian card that has the correct firmware for the Zero here. Or you can pick up an 8G card with NOOBS 2.0. Or use a blank 4G SD card and burn in Raspbian Wheezy and update the firmware. Make sure you have the latest version!
- Mini HDMI to HDMI Adapter - Will let you convert the little port on the Zero to a standard sized HDMI jack. You can get 1080P HDMI video + audio out of this little computer!
- USB OTG Cable - Lets you plug in a normal USB device such as WiFi dongle, USB hub, keyboard, mouse, etc into the Zero.
- USB Console cable - if you're not going to stick an HDMI monitor on there, then this is essential, you connect the wires to the GPIO pins and log in over a serial console. Its the easiest & fastest way to get on your Pi
- 2x20 Male header strip - Solder this in to plug in Pi HATs, GPIO cables, etc as you would into a normal Pi. (We also have a 2x20 Female and 2x20 Female right-angle style for more exotic connecting)
To keep the price and size as small as possible, there is a spot on the Zero for a 2x20 pin header. This header is not included or soldered on. Creative individuals can easily solder in a set of 2x20 male header strip so you can plug in any sort of Pi HAT or other plug-in topper. Or, go with a 2x20 female header and plug the Pi Zero directly into an Adafruit Cobbler or T-Cobbler.
Please note: Some boards are made in the UK, some in China. WE DO NOT KNOW IN ADVANCE WHICH ONES YOU MAY RECEIVE!
Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
