The Crazyradio is a 2.4 GHz radio USB dongle. Currently it's only used to communicate with the Crazyflie Nano Quadcopter but it can be adopted to work with a number of applications that are based on the low-cost 2.4 GHz chips from Nordic Semiconductor.

Features

• Based on the nRF24LU1+ 2.4 GHz SoC from Nordic Semiconductor
• USB bootloader enables firmware upgrades via USB
• Can be used as stand-alone module with RC controller via expansion header. Supports 12V PPM input and power supply. Note: There's still no firmware to support this feature but it's under development
• Comes with GPLv3 firmware developed fully by Bitcraze from datasheet and a build environment that allows you to develop your own firmware
• Programmable via SPI using expansion header

• Install crazyradio driver on Windows XP to 10 (This is now the recomended procedure)
• Install crazyradio driver on Windows 7 (legacy)
• Install crazyradio driver on Windows 8 (legacy)
• Firmware upgrade
