The Crazyflie Bolt is currently part of our early access program. To better understand what this means also have a look at our Product cycle.

Crazyflie Bolt

The Crazyflie Bolt is a Crazyflie 2.X compatible flight controller for brushless builds. It is intended to have the strengths of the Crazyflie 2.1 but in a slightly bit bigger package.

The size of the board is 36mm x 35.4mm and the holes are M3, located at the common 30.5mm square, to fit most frames.

Specification

Please see the shop product page for full specification <add link>.

Features and differences from Crazyflie 2.1

  • Fully compatible with the CF2 firmware, expansion decks as well as radio.
  • Connectors to attach motor controllers (also possible to solder) so it is easy to build and repair.
  • Power distributions built into controller board. (Max ~8A per motor controller) with XT30 connector.
  • Motor controllers can be switched off by the system (MOSFET) so the system can go into deep sleep and only consume around 50uA.
  • Voltage input 1S-4S (3V to 17V).
  • External antenna for increased range with possibility to use diverisy (two antennas).
  • SPI connected IMU (BMI088) for minimum latency.
  • Not using any deck expansion pins as the Big-quad deck does
  • Can run brushed motors as well
  • Can measure battery voltage (but not current)
  • Can be powered from external 5V as well when using external PDB

Power

The Bolt contains a power distribution board (PDB) but it is a bit limiting. Both as the current has to pass a MOSFET and the ESC connector. We have tested running 8A though the chain without any limiting heat-up but that is as far as we would recommend to go. If increased current is wanted one could bypass the connectors by soldering the ESC directly to the connector soldering pad. The MOSFET is still there but a slight increase should be possible. For higher currents, an external PDB should be used. Other tricks to keep current down, but power up, is to run on higher voltage (3S or 4S) and using low KV motors.
