The Raspberry Pi Zero 2 W

In this article we will look at the Raspberry Pi Zero 2 W and its various features, first an image of the board in question

First lets look at some of the specifications

  • Processor :  64-bit ARM BCM2710A1 Cortex-A53 CPU with a 1GHz quad-core
  • Graphics : 500 MHz VideoCore VI
  • Memory : 512mB
  • Ports : Mini HDMI and USB 2.0 OTG ports
  • Micro USB power
  • MicroSD slot
  • 802.11b/g/n wireless LAN
  • Standard 40 pin GPIO connector
  • Bluetooth 4.2 / Bluetooth Low Energy (BLE)
  • Interfaces : CSI (camera)
  • Composite video and reset pins are available via solder test points
  • Price : about £15


The processor is a quad core 1.5GHz Cortex-72. This processor has about 40% more single-threaded performance, and five times more multi-threaded performance, than the original single-core Raspberry Pi Zero. It can be overclocked to 1.2Ghz.

This board has three more cores that the original Pi Zero


The graphics chip is a 500 MHz VideoCore VI.

I had no luck playing any Youtube videos at 1080p and even 720p – I do not think this board is suitable for that function but of course may be wrong.


Unlike the Raspberry Pi 4 which has 4 memory options the Pi Zero 2 W only comes with 512mB. Something that you need to factor in when you choosing a board for whatever function you need it for.

Using this as a desktop replacement may be out of the question here.


You get Bluetooth 4.2 and BLE as options and there is also support for WiFi connectivity via the 802.11b/g/n wireless LAN, this is an advantage over the very first Pi Zero which had no connectivity out of the box.

Its also a slight upgrade from 4.1 to 4.2 on the Pi Zero W


You get 1 Mini HDMI  port

You get 2 USB ports, one of these is for a USB 2.0 OTG ports and the other i sised for powering the board.

The GPIO port is backwards compatible with previous models which is all important for me with all of the hats that I already have.

It has a MIPI CSI camera interface so your existing Raspberry Pi camera should work just fine with an adaptor

A more powerful Zero base board which is ideal for small projects like basic retro gaming handhelds such as GBA, GBC or DS. IoT projects and

The board has the same form factor as previous Pi Zero boards so your existing case should fit just fine.


Memory is limited to 512mB and desktop applications may struggle to run fluidly.

No GPIO header fitted

You may need a heatsink on the CPU as it can run 20 degress warmer than the previous board – you may not have needed this with previous boards
