The Crazyradio is the official radio dongle for the Crazyflie Nano Quadcopter. It is a 2.4GHz USB radio dongle based on the nRF24LU1+ chip from Nordic Semiconductor.

The design includes a 2x5 header (not mounted) where the dongle can be connected and powered from another source than USB. It also has two indicator LEDs.

The dongle is delivered with open source firmware and Python drivers that enables easy use. The dongle can communicate with any project using a compatible Nordic Semiconductor radio chip. The firmware can be freely modified as it is open source and can be compiled with an open source compiler (sdcc).

A bootloader on the dongle enables firmware updates without using any external programmer. It can also be programmed over SPI, which is available in the header. This is recommended when developing for it.

Crazyradio features:

• 2.4GHz radio communication
