Crazyflie Bolt 1.1 – Flight controller for brushless drones

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.
