Rascals are always sociable, and the chief sign that a man has any nobility in his character is the little pleasure he takes in others company. Arthur Schopenhauer


ChipWhisperer is an open source toolchain dedicated to hardware security research. This toolchain consists of several layers of open source components:

  • Hardware: The ChipWhisperer uses a capture board and a target board. Schematics and PCB layouts for the ChipWhisperer-Lite capture board and a number of target boards are freely available.

  • Firmware: Three separate pieces of firmware are used on the ChipWhisperer hardware. The capture board has a USB controller (in C) and an FPGA for high-speed captures (in Verilog) with open-source firmware. Also, the target device has its own firmware; this repository includes many firmware examples for different targets.

  • Software: The ChipWhisperer software includes a Python API for talking to ChipWhisperer hardware (ChipWhisperer Capture) and a Python API for processing power traces from ChipWhisperer hardware (ChipWhisperer Analyzer). You can find documentation for our Python API at
