This product is in early access stage. It means that while the hardware is working and tested, the software is still pretty much work in progress. For more information see the early access description page.

The Crazyflie Bolt is a Crazyflie 2.X compatible flight controller for brushless builds. It is intended to have the strengths of the Crazyflie 2.1, but in a slightly bit bigger package. It uses the same sensors as the Crazyflie 2.1 and the firmware binaries are compatible with both.
