+Crazyradio 2.0 is a long range open USB radio dongle based on the nRF52840 from Nordic Semiconductor, featuring a
+20dBm power amplifier and LNA.
+{% enddatasheet_intro %}
+
+## Introduction
+
+The Crazyradio 2.0 is not only for usage together with the Crazyflie family of devices, since
+it's an open project with open firmware and a Python API, it's a great
+building block for systems that require more predictable latency compared to WiFi and doesn't have the same
+requirements for bandwidth. The hardware comes with a
+bootloader that enables firmware upgrades via USB without any additional hardware needed.
+
+The Crazyradio 2.0 is compatible with the Crazyflie eco system.
