The project has been developed to run on a Raspberry Pi 0 W configured as an [USB Ethernet gadget](https://learn.adafruit.com/turning-your-raspberry-pi-zero-into-a-usb-gadget/ethernet-gadget) device in order to connect to it via USB. However, given the proper configuration tweaks, any GNU/Linux computer with a WiFi interface that supports monitor mode could be used.
**An important note about the AI:** a network trained with a specific WiFi interface will ONLY work with another interface if it supports the *exact same* WiFi channels of the first one. For instance, you CANNOT use a neural network trained on a Raspberry Pi Zero W (that only supports 2.4Ghz channels) with a 5Ghz antenna; you will need to train one from scratch for those channels.
The display is an optional component as the UI is also rendered via a web interface available via the USB cable. If you connect to `usb0` (by using the data port on the unit) and point your browser to the web ui (see `config.yml`), your unit can work in "headless mode".
**One thing to note:** Not all displays are created equally! TFT displays, for example, work similar to an HDMI display, and they are NOT supported. Currently, all the officially-supported displays are I2C displays. If you are still interested in using unsupported displays, you may be able to find a community-submitted hack in the [Screens](https://github.com/evilsocket/pwnagotchi/blob/master/docs/hacks.md#screens) section of the [Hacks](https://github.com/evilsocket/pwnagotchi/blob/master/docs/hacks.md) page. We are not responsible for anything you break by trying to use any display that is not officially supported by the development team!
Some of the supported displays support both **Black & White** and **Colored** versions. One common question whether there are meaningful differences between the two. There are:
- Color displays have a much slower refresh rate. In some cases, it can take up to 15 seconds; if slow refresh rates are something that you want to avoid, we recommend you use B&W displays.
- The 3-color 2.13" Waveshare displays have a slightly smaller pixel layout (104x212) compared to their B&W counterparts (122x250).
- Avoid the Waveshare eInk **3-color** display. The refresh time is 15 seconds.
- Avoid the Pimoroni Inky pHAT **v1.** They're discontinued due to a faulty hardware part source used in manufacturing that resulted in high failure rates.
- Many users seem to prefer the Inky pHATs. There are two primary reasons:
- The Inkys feature better documentation and SDK support.
- Many Waveshare resellers do not disclose the version of the Waveshare boards they are selling (v1 vs v2), and the type they are selling can be fairly unclear (i.e., Waveshare 2.13 vs 2.13 B vs. 2.13C, and so on.)
The easiest way to create a new Pwnagotchi is downloading the latest stable image from [our release page](https://github.com/evilsocket/pwnagotchi/releases) and write it to your SD card. You will need to use an image writing tool to install the image you have downloaded on your SD card.
[balenaEtcher](https://www.balena.io/etcher/) is a graphical SD card writing tool that works on Mac OS, Linux and Windows, and is the easiest option for most users. balenaEtcher also supports writing images directly from the zip file, without any unzipping required.
