We recommend using Python 3.7 as it seems to have the best general compatability; however, any version >= 3.6 should work. Python 2.x does NOT work with this codebase.

If you’re using our virtual machine or Windows installer, you can proceed directly to Installation. Otherwise, select our operating system below for instructions on installing required software for ChipWhisperer:


There is only manual install available on GNU/Linux, besides the VM; however, it is much easier to grab all the required prerequisites than on Windows.

Quick Install

The following commands are provided if you want to get right into using ChipWhisperer. They have been tested on Lubuntu 21.04 and required steps may differ on other distributions of Linux.

sudo apt update && sudo apt upgrade
sudo apt install python3 python3-pip libusb-dev make git avr-libc gcc-avr gcc-arm-none-eabi libusb-1.0-0-dev
sudo bash -c 'printf "SUBSYSTEM==\"usb\", ATTRS{idVendor}==\"2b3e\", ATTRS{idProduct}==\"*\", TAG+=\"uaccess\"\\n" >> /etc/udev/rules.d/50-newae.rules'
sudo bash -c 'printf "SUBSYSTEM==\"tty\", ATTRS{idVendor}==\"2b3e\", ATTRS{idProduct}==\"*\", TAG+=\"uaccess\", SYMLINK+=\"cw_serial%n\"\\n" >> /etc/udev/rules.d/50-newae.rules'
sudo bash -c 'printf "SUBSYSTEM==\"tty\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"6124\", TAG+=\"uaccess\", SYMLINK += \"cw_bootloader%n\"\\n" >> /etc/udev/rules.d/50-newae.rules'
sudo udevadm control --reload-rules
sudo usermod -a -G dialout $USER

Once that’s done, you should logout and login, or reboot your system.

You are now ready to move on to ChipWhisperer.

We go through each of these commands below:

Update Packages

Make sure your packages are up to date before installing anything

sudo apt update && sudo apt upgrade


On Linux installing Python and the the associated package is straightforward. Typically, you can install them from the package manager (ie. apt-get, yum, …).

On Ubuntu or similar:

sudo apt install python3 python3-pip


There are some packages required for chipwhisperer and its dependencies such as libusb1 to work. Install using:

sudo apt install libusb-dev make libusb-1.0-0-dev

You’ll probably want to pick up git as well:

sudo apt install git


The AVR Toolchain can be installed using:

sudo apt install avr-libc gcc-avr

The Arm Toolchain can be installed using:

sudo apt install gcc-arm-none-eabi

Hardware Drivers

The driver for Linux is built in; however, you need to allow your user account to access the peripheral. To do so, you’ll have to make a file called /etc/udev/rules.d/50-newae.rules. The contents of this file should be:

# Match all CW devices
SUBSYSTEM=="usb", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="*", TAG+="uaccess"
SUBSYSTEM=="tty", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="*", TAG+="uaccess", SYMLINK+="cw_serial%n"
SUBSYSTEM=="tty", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="6124", TAG+="uaccess", SYMLINK+="cw_bootloader%n"

The following commands will put this into the proper file:

sudo bash -c 'printf "SUBSYSTEM==\"usb\", ATTRS{idVendor}==\"2b3e\", ATTRS{idProduct}==\"*\", TAG+=\"uaccess\"\\n" >> /etc/udev/rules.d/50-newae.rules'
sudo bash -c 'printf "SUBSYSTEM==\"tty\", ATTRS{idVendor}==\"2b3e\", ATTRS{idProduct}==\"*\", TAG+=\"uaccess\", SYMLINK+=\"cw_serial%n\"\\n" >> /etc/udev/rules.d/50-newae.rules'
sudo bash -c 'printf "SUBSYSTEM==\"tty\", ATTRS{idVendor}==\"03eb\", ATTRS{idProduct}==\"6124\", TAG+=\"uaccess\", SYMLINK += \"cw_bootloader%n\"\\n" >> /etc/udev/rules.d/50-newae.rules'

Alternatively, you can just copy chipwhisperer/hardware/50-newae.rules to /etc/udev/rules.d/.

Next, reset the udev system:

sudo udevadm control --reload-rules

Finally log out & in again for the group change to take effect.

You can always find the latest version of this file on Github.

You should also add your username to the dialout group, which will allow you to reprogram the USB firmware on your ChipWhisperer and use the ChipWhisperer’s serial port:

sudo usermod -a -G dialout YOUR-USERNAME

Once that’s done, reboot your system, or logout and login again.


You are now ready to move on to ChipWhisperer.

Windows Manual

Starting with ChipWhisperer 5.5, all of the Windows prerequisites will can be installed by using our Windows Installer. If you don’t want to use our installer, you should grab the following programs:


For any of the other installation methods, you’ll need to have Python 3 installed on your computer. If you already a recent version of Python installed (3.6.x+), you can skip this step.

The recommend method of installing Python is to use a distribution called WinPython. This setup avoids installing Python globally, and includes most of the software you will need. In addition it makes it possible to install 32-bit and 64-bit Python on the same system with minimal problems. This can be very useful as the 64-bit version is handy for doing analysis on large data sets.

To install WinPython 3.7.x, Download a release in the 3.7.x branch from the WinPython site. ChipWhisperer works with both 32-bit and 64-bit versions of Python.

Choose a reasonable location to install this to - note the default is simply in the download directory. Instead it’s recommended to find a directory such as /WinPython32bit-, or into your local directory such as c:/Users/yourname/WinPython32bit-

Go to your installation directory for WinPython, and run the shortcut called WinPython Command Prompt.exe. This will give you a command prompt which is setup to run Python along with associated scripts.

Optional: You can add the python.exe you just installed to your PATH. To do so navigate to your installation folder, and run the WinPython Control Panel.exe program. Then select Advanced -> Register distribution. If you do not do this, you will have to run all commands in this document via the WinPython Command Prompt.exe. If you plan on running both 32-bit and 64-bit Python, you should not register them. Instead explicitly call the correct Python by always running the WinPython Command Prompt.exe, and then calling specific scripts or notebooks.

Installing Hardware Drivers

As of ChipWhisperer firmware *.23, your ChipWhisperer will automatically configure as a WinUSB device, meaning no manual driver installation is required.

If your ChipWhisperer has older firmware, see our driver help page.


To build firmware for target boards, you’ll need to install GNU Make. There’s a couple of ways you can install make:

  • Install MinGW and add MinGW\msys\1.0\bin to your path.

  • Install Cygwin, install make, and add cygwin\bin to your path.

  • Install avr-gcc and add avr-gcc-xx.x.x-x64-windows\\bin\\ to your path.


It assumed any time the make command is run, that the appropriate compiler is on the path, whether that is the ARM toolchain or avr-gcc. You’ll need to add the bin folder from your avr-gcc installation to your path.


Remember that any time you install packages for python during the installation, use the WinPython Command Prompt.exe.You are ready to move on to ChipWhisperer.

Mac OS X

The Mac OS X instructions are similar to the GNU/Linux once you have brew installed.


Open your bash terminal and paste this into the prompt:

/usr/bin/ruby -e "$(curl -fsSL"

This snippet is taken directly from brew’s website. The script will guide you through the installation.


libusb is required by the chipwhisperer software to communicate with the board. You can install it using brew:

brew install libusb


The best way to install Python on Mac is in a Python virtualenv. The steps for this are found at A quick summary is:

brew install pyenv
pyenv install 3.7.7
pyenv global 3.7.7
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.zshrc

Then launch a new terminal and run

python --version

and make sure it reports that you’re using Python 3.7.7.


The compilers are also available on Mac OSx. The ARM compiler can be found on the ARM website. If needed, the AVR compiler can be installed as well using:

brew tap osx-cross/avr
brew install avr-gcc

This brew install does not work for some older versions of Mac OS X. You will have to find a different way to install the compilers.


You are now ready for installing ChipWhisperer.
