CC3D Openpilot Open Source Flight Controller 32 Bits Processor for QAV250 C250 250 Quadcopter

CC3D CopterControl Hardware Features
Powerful STM32 32-bit microcontroller running at 90MIPs with 128KB Flash and 20KB RAM.
3-axis high-performance MEMs gyros and 3-axis high-performance MEMs accelerometer.
Tiny 36mmx36mm 4 layer PCB for superior electrical noise reduction and flight performance.
Software support for Windows, Mac and Linux.
Direct high speed USB support with no drivers required, a truly plug and play device.
Spektrum satellite receiver support.
Futaba S-BUS hardware support.
Innovative Flexi-port technology for superior port flexibility.
4Mbits on-board EEPROM for configuration storage.

Flexiport
CopterControl also offers the innovative Flexi-port which provides either I2C connectivity or a second serial port. Flexi-port gives CopterControl the flexibility to use either I2C and a single serial port or dual serial ports, according to your connectivity needs.
 
Superior user experience
OpenPilot has tried to make your experience with the CC3D as easy and trouble-free as possible. Naturally for a high-end product, the hardware is complete; there is nothing to solder. The included RC harness allows you to connect any standard PWM receiver. All CopterControl boards are tested before shipping and come with bootloader already flashed. A standard mini-USB cable (not included) is used to load the latest firmware and configure everything for your unique airframe.
 
The OpenPilot project, whist still young, it trying to make Open Source much more user friendly. OpenPilot software is designed to be used by everybody! All major operating systems are supported and install packages are provided. The software is all Free software under the GPLv3 license and not only are you welcome to hack it, but we encourage it!
