The open-source C++ programmable drone kit for university students, makers and developers.
LiteBee Crazepony C+
Built for Developers
Crazepony C+ is a fully open-source micro quadcopter built around a 32-bit ARM Cortex-M3 processor. The hardware schematics, flight controller firmware, and Windows tuning utility are all open and freely available on GitHub — so you can read every register, modify every PID value, and make the aircraft truly yours.
OOpen Source C+ Code Hackable
Highlights That Matter
Every feature on Crazepony C+ is designed to give developers transparent, hackable control over a real flying robot.
High-Performance Processor
72 MHz 32-bit ARM Cortex-M3 runs flight code in real time.
Palm-Sized Frame
117 mm wheelbase — a true pocket drone for lab and demo flights.
6-Axis Stabilization
MPU-6050 IMU delivers stable hovering and responsive control.
PC Tuning Station
Windows utility for live telemetry, attitude data and PID tuning.
Multi-Protocol Wireless
2.4G nRF24L01+, classic Bluetooth and BLE 4.0 built in.
100% Open Source
Full firmware and hardware files on GitHub — fork and modify.
Engineered for Tinkering
Crazepony C+ looks compact, but it’s a serious embedded system. The flight-control loop runs on a 72 MHz ARM Cortex-M3, the sensor data is fully exposed over I2C, and the Windows tuning utility gives you live access to every PID parameter — no black boxes.

An Open-Source Developer Path
Crazepony C+ is not a step-by-step toy course — it’s a self-directed engineering journey from reading schematics to shipping your own firmware.
University Labs
Embedded systems, control theory and robotics lab courses for engineering undergraduates.
Graduation Projects
Thesis work on flight control, sensor fusion, wireless protocols or swarm algorithms.
Robotics Clubs
Hands-on projects for student teams preparing for UAV and robotics competitions.
Maker Communities
Hackathons, maker fairs and open-source events where code meets flight.
Certified for Classrooms
Every LiteBee product meets international safety and quality standards — independently tested and backed by full documentation for school procurement.
