Sometimes LED feedback isn’t enough, like when you’re flying around in a lab or a living room. With the buzzer deck you’ll get audio feedback on system events, like low battery or charging completed. Or why not create your own melodies that will play while you’re buzzing around? To get started using the buzzer deck there’s already a few melodies pre-programmed in the Crazyflie 2.X firmware.
For more information, see the Buzzer deck web page.
