Crazyradio 2.0 is a USB radio dongle providing long-range, wireless control and communication with Crazyflie 2.X. It features a 20dBm power amplifier and LNA, offering an open project with open firmware and a Python API for applications requiring predictable latency and not large bandwidths.
Note
Crazyradio 2.0 utilizes an updated nRF52 chipset, which is not compatible with custom firmware developed for the nRF24 MCU in the Crazyradio PA, such as security firmware projects.
Feature
Strong Output Power: Radio power amplifier giving 20dBm output power
Abundant resources: Open source firmware and firmware upgrade via USB
Low latency : 2Mbps, 1Mbps and 250Kps can reduce the delay rate between communications
Debug connector

FAQ
- For how long can the Crazyflie 2.X fly?
It can fly up to 7 minutes and depending on how you fly it, the time will decrease.
- How is the Crazyflie 2.X charged?
It is charged using a standard micro-USB connector commonly used by smartphones. You probably have one of these cables at home. You can charge it from any USB unit that can supply 500mA, most computers and adapters do. It takes up to 40min to charge and the blue LED (M3) will tell you roughly how charged it is by how long it is lit. When it is fully lit it is fully charged.
- Can I hot swap batteries on the Crazyflie 2.X?
Yes, you can hot swap batteries.
- Can I use a bigger battery on the Crazyflie 2.X?
Yes, as long as it is not too heavy, it is a single cell (3.7V), it fits and the polarity is correct you can do so. A higher capacity battery will give you longer flight times but will also decrease agility. We recommend batteries with at least 15C continuous discharge rate.
