Via the micro USB power interface It runs at 5.2V. Bluetooth and app controlled robots can be easily made using the Raspberry Pi Zero W as the brain and add on boards called HATs / pHATs are used to provide features like motor control and sensors.Īnother key feature of the Raspberry Pi Zero is that it is a low power computer. Robotics projects are another area where the Raspberry Pi Zero W is strong, again due to its size and connectivity. Old technology such as printers can be upcycled into wireless printers available to all our devices by connecting a Raspberry Pi Zero W and running some simple code. There is enough power to run our code, process the results and upload for later analysis, all via this tiny computer. ![]() The price and size of the Raspberry Pi Zero make it ideal for embedded projects such as data collection, home automation and body cameras. You’ll need a mini HDMI to HDMI cable or adapter to connect to a monitor or TV. Obscure video port: Very few devices use mini HDMI, but the Raspberry Pi Zero is one of them.Special camera cables: You’ll need special Pi Zero camera cables if you want to use a Raspberry Pi camera module.But look at this as an opportunity to learn soldering, and with one of the best soldering irons from our list, you will make short work of the 40 pin GPIO. There are also some solder-free ways to attach pins. Bring your own pins: The GPIO does not come pre-soldered, though you can find some stores that sell pre-soldered models for extra.One data port: There is a single micro USB port for data (plus one for power), so to connect a keyboard and mouse we either need a USB hub or to use Bluetooth peripherals.To save the money and size over a full-fledged Raspberry Pi 4, you have to make some compromises. When thinking about the Raspberry Pi Zero there are some caveats to consider. This model has been replaced so you’re unlikely to see it for sale anywhere.Īll three models share the same layout, size and HDMI / USB ports and if you are thinking of purchasing your first board then the Raspberry Pi Zero W should be your only consideration. Raspberry Pi Zero (version 1.2): The original version of the Pi Zero lacked the CSI camera connector that version 1.3 and Pi Zero W have.Raspberry Pi Zero (version 1.3) : The current version of the Zero lacks wireless connectivity, but has an MSRP of just $5, which makes it attractive for a project where you either don’t need network access or can have it USB connected to a PC.Raspberry Pi Zero W : Clearly the best choice, but with an MSRP of $10, slightly more expensive than the regular Pi Zero, this version includes Wi-Fi and Bluetooth connectivity.There are three models of Raspberry Pi Zero, though only two of them are current. In the browser of your desktop system, within a few minutes you will be able to reach your new Home Assistant at homeassistant.local:8123.40 GPIO Pins, CSI camera connector (not on version 1.2)Ģ.6 x 1.2 x 0.2 inches (66.0mm x 30.5mm x 5.0mm) Plug in an Ethernet cable that is connected to the network.Ĭonnect the power supply to start up the device. Insert the SD card into your Raspberry Pi. Wait for the Home Assistant OS to be written to the SD card.Note: the contents of the card will be overwritten. Choose the Home Assistant OS that matches your hardware (RPi 3 or RPi 4).Select Other specific-purpose OS > Home assistants and home automation > Home Assistant.Download and install the Raspberry Pi Imager on your computer as described under.If Raspberry Pi Imager is not supported by your platform, you can use Balena Etcher instead. This guide shows how to install the Home Assistant Operating system onto your Raspberry Pi using Raspberry Pi Imager. After installation, Home Assistant can work with Wi-Fi, but an Ethernet connection is more reliable and highly recommended. The brand doesn’t matter, just pick the cheapest. This is already part of most laptops, but you can purchase a standalone USB adapter if you don’t have one. Ideally get one that is Application Class 2 as they handle small I/O much more consistently than cards not optimized to host applications. Power Supply for Raspberry Pi 4 or Power Supply for Raspberry Pi 3.Raspberry Pi are currently hard to come by, use RPilocator to find official distributors with stock. Raspberry Pi 4 (Raspberry Pi 3 is ok too, if you have one laying around).If you’re not in the US, you should be able to find these items in web stores in your country. We will need a few things to get started with installing Home Assistant. ![]() ![]() USB ports on your computer also will not supply enough power and must not be used. Mobile chargers may not be suitable, since some are designed to only provide the full power with that manufacturer’s handsets. Please remember to ensure you’re using an appropriate power supply with your Raspberry Pi.
