The Crazyflie 2.0 is nice little open source quadcopter. Yes it runs Paparazzi to. It is a Work In Progress, together we get there. Expect it soon to apear in Paparazzi master. We first need some testflights,indeed.


  • Easy to assemble and no soldering required
  • WIP: Wireless firmware updates
  • On-board charging via standard uUSB
  • Dual-MCU architecture with dedicated radio/power management SoC for advanced applications
  • All the Real-time logging, graphing and variable setting as one is used to with Paparazzi

Mechanical specifications

  • Weight: 27g
  • Size (WxHxD): 92x92x29mm (motor-to-motor and including motor mount feet)

Radio specifications

  • 20 dBm radio amplifier
  • Bluetooth Low Energy support


  • STM32F405 main application MCU (Cortex-M4, 168MHz, 192kb SRAM, 1Mb flash)
  • nRF51822 radio and power management MCU (Cortex-M0, 32Mhz, 16kb SRAM, 128kb flash)
  • uUSB connector
  • On-board LiPo charger with 100mA, 500mA and 980mA modes available
  • Full speed USB device interface


  • 3 axis gyro (MPU-9250)
  • 3 axis accelerometer (MPU-9250)
  • 3 axis magnetometer (MPU-9250)
  • high precision pressure sensor (LPS25H)

Flight specifications

  • Maximum payload weight: ~10 g

Expansion connectors

  • VCC (3.0V, max 100mA)
  • GND
  • VCOM (unregulated VBAT or VUSB, max 1A)
  • VUSB (both for input and output)
  • I2C (400kHz)
  • SPI
  • 2 x UART
  • 4 x GPIO/CS for SPI
  • 1-wire bus for expansion identification
  • 2 x GPIO connected to nRF51



For now flashing is via an USB cable in the DFU mode. Press and hold the Reset button while insering the USB into your PC. Then Clcik UPload in Paparazzi Center


With e.g. great BlackMagicProbe JTAG adapter development can be smoother than without.



A light GPS


One can add one of thos small ESP based Wifi modules described here
