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 1.1 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. The Crazyflie Bolt 1.1 runs the same firmware base as the Crazyflie 2.1 and includes the same IMU. So you can start out developing using the much smaller Crazyflie 2.1 and then grow as your application grows.
