The “vanilla” hardware setup for a Pwnagotchi is a Raspberry Pi 0 W (usually referred to as
RPi0W throughout this documentation). Most development and testing has been conducted on Pwnagotchis living in RPi0W bodies configured as an USB ethernet gadget device (in order to connect to it via USB). That said:
The microSD card ought to be:
If you’re going to be taking your Pwnagotchi out into the world to find new and exciting WiFi environments (!), you’re going to need to power it with an external battery. Depending on your priorities, you may only need a small battery if you’re just going to be out for a couple hours. But if you’re going to be out all day, you might need something bigger. How do you know what you’ll need to keep your Pwnagotchi pwning?
Happily, our users have submitted some preliminary benchmarks using some popular batteries to help give you a sense for how long a particular battery is likely to be able to power your Pwnagotchi when you take it out into the WiFi wilderness. :)

UPS-Lite V1.1 is nice and feature-rich battery hat. It has battery charge controller which communicate over I2C interface and can tell its’ voltage level. It also has built-in UART->USB adapter connected to raspbbery UART pins so you can connect to serial console using the same microUSB port while charing the battery.
Pwnagotchi has a
ups_lite plugin to display battery on the screen. Before using it i2c interface should be enabled in
If you’re using a Raspberry Pi 0 W for the body of your Pwnagotchi, you should be aware of the fact that it does not have an hardware clock. This means that unless it’s connected to the internet somehow (either by USB cable and host connection sharing or BT tethering), when the unit is off its time will go out of sync with the real world, presenting wrong uptimes and generally using wrong date and times in the logs and whenever another absolute-time-based action is performed.
This problem can be solved for cheap with an hardware clock, a small chip with a battery that can stay on while the rest of the unit is off … it’s like giving your Pwnagotchi a wristwatch! :D
Any I2C compatible model can be used (usually PCF8523, DSL1307 or DS3231 based) and easily installed by following this guide.
Usually they would be plugged directly to the GPIO via their connector but it is possible to desolder the connector and just solder them directly to the ports on the PCB in order to save space (make sure to isolate the chip with duct tape).
If you want to use the web UI (instead of an e-ink display attached to your unit's RPi0W) to see your Pwnagotchi's face, check out the web UI doc for more details on using the web UI.
If, instead, you want to fully enjoy walking around and literally looking at your unit’s cute af face, the supported e-ink display models are:
Before purchasing a display, see Recommendations for more details about choosing the right display. If you find yourself struggling with the screen you’ve chosen, there are dedicated #waveshare and #inky channels for troubleshooting in the Pwnagotchi Slack.
Needless to say, we are always happy to receive pull requests updating support for existing models as well as adding support for new models. ❤️
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 eInk displays are SPI displays. If you are still interested in using unsupported displays, you may be able to find a community-submitted hack in the Screens section of the Hacks 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:
screen_refreshto redraw the screen after a configurable amount of screen updates.
We recommend housing your Pwnagotchi’s body in a case if you don’t want your Pwnagotchi to get dirty (or short the GPIO pins on the back, or be mistaken for a bomb…).
If you’re running your Pwnagotchi in headless mode (AKA without a screen) and are using its web UI instead of an e-ink screen, any generic case for a RPi0W ought to do the trick. But if you’ve installed an e-ink screen on your RPi0W in order to view your Pwnagotchi’s face without any external equipment, you’ll probably need to make or acquire a custom case.
A few users have already designed custom cases you can 3D print (If you don’t have access to a 3D printer yourself, you can use a service like Shapeways or treatstock.com to have a case printed on demand):
If you’re looking for a ready-made case that fits (albeit bulkily):
There are many creative Pwnagotchi case set-ups. We have a dedicated
#cases channel in our Slack for all your case-related discussion needs!
The easiest way to create a new Pwnagotchi is downloading the latest stable image from our release page and writing it to your SD card.
Once you have downloaded the latest Pwnagotchi image, you will need to use an image writing tool to install that image on your SD card. We recommend using balenaEtcher, a graphical SD card writing tool that works on Mac OS, Linux, and Windows; it is the easiest option for most users. (balenaEtcher also supports writing images directly from the ZIP file, without any unzipping required!)
To write your Pwnagotchi image with balenaEtcher:
.zipfile you wish to write to the SD card.
Flash!to begin writing data to the SD card.
As an alternative you can use dd on GNU/Linux or macOS:
Change the path to your image file,
/dev/sdcard is the path to you SD card device.
dd if=path/to/pwnagotchi-raspbian-lite-XXX.img of=/dev/sdcard bs=1M
Wait before removing the SD card as you will need to create one last file on it with the initial configuration.
If instead of using our image you prefer the hacker way and you want to configure the software components manually on any GNU/Linux box, you will need to follow these steps.
First of all, download and install bettercap, its caplets and its web ui (change the URL to match the precompiled binary of the latest release according to your architecture):
wget "https://github.com/bettercap/bettercap/releases/download/v2.26/bettercap_linux_amd64_v2.26.zip" unzip bettercap_linux_amd64_v2.26.zip # ... check the sha256 digest before doing this ... sudo mv bettercap /usr/bin/ # install the caplets and the web ui in /usr/local/share/bettercap and quit sudo bettercap -eval "caplets.update; ui.update; quit"
Depending on the name of the WiFi interface you’re going to use, you’ll need to edit the
/usr/local/share/bettercap/caplets/pwnagotchi-manual.cap caplet files accordingly.
How to run bettercap and in which mode it’s up to you as long as it’s running one of those two caplets. In the default Pwnagotchi image bettercap is running as a systemd service through a launcher script.
[Unit] Description=bettercap api.rest service. Documentation=https://bettercap.org Wants=network.target After=pwngrid.service [Service] Type=simple PermissionsStartOnly=true ExecStart=/usr/bin/bettercap-launcher Restart=always RestartSec=30 [Install] WantedBy=multi-user.target
And this is
#!/usr/bin/env bash /usr/bin/monstart if [[ $(ifconfig | grep usb0 | grep RUNNING) ]] || [[ $(cat /sys/class/net/eth0/carrier) ]]; then # if override file exists, go into auto mode if [ -f /root/.pwnagotchi-auto ]; then /usr/bin/bettercap -no-colors -caplet pwnagotchi-auto -iface mon0 else /usr/bin/bettercap -no-colors -caplet pwnagotchi-manual -iface mon0 fi else /usr/bin/bettercap -no-colors -caplet pwnagotchi-auto -iface mon0 fi
Even in this case the interface name and the command to start the monitor mode need to be adjusted for the specific computer and WiFi card.
Note: you need also libpcap to be installed
The second service you will need is pwngrid, even in this case:
wget "https://github.com/evilsocket/pwngrid/releases/download/v1.10.1/pwngrid_linux_amd64_v1.10.1.zip" unzip pwngrid_linux_amd64_v1.10.1.zip # ... check the sha256 digest before doing this ... sudo mv pwngrid /usr/bin/ # generate the keypair sudo pwngrid -generate -keys /etc/pwnagotchi
Pwngrid runs via the
/etc/systemd/system/pwngrid-peer.service systemd service:
[Unit] Description=pwngrid peer service. Documentation=https://pwnagotchi.ai Wants=network.target [Service] Type=simple PermissionsStartOnly=true ExecStart=/usr/bin/pwngrid -keys /etc/pwnagotchi -address 127.0.0.1:8666 -client-token /root/.api-enrollment.json -wait -log /var/log/pwngrid-peer.log -iface mon0 Restart=always RestartSec=30 [Install] WantedBy=multi-user.target
The last ingredient of this soup is going to be the python3 Pwnagotchi main codebase, that for any release can be installed with:
wget "https://github.com/evilsocket/pwnagotchi/archive/v1.0.1.zip" unzip v1.0.1.zip cd pwnagotchi-1.0.1 # this will install the requirements and pwnagotchi itself sudo pip3 install .
Assuming both bettercap and pwngrid are configured and running correctly, you can now start pwnagotchi by simply:
# AUTO mode sudo pwnagotchi # AUTO mode with debug logs sudo pwnagotchi --debug # MANU mode sudo pwnagotchi --manual # MANU mode with debug logs sudo pwnagotchi --manual --debug # show the other options pwnagotchi -h
This will install the default configuration file in
/etc/pwnagotchi/default.yml, in order to apply customizations you’ll need to create a new
/etc/pwnagotchi/config.yml file as explained in the configuration section.
(But should apply to Pi4 as well)
You can follow the main Pi0w installation instructions with just a couple of notes:
/boot/config.txtand add/uncomment the
arm_freq=800line. Don’t forget to add this file to your backups;
